  1. Jenny came into the store with $90. the way i got this is: $9.95 x 7 = $69.65 $69.65 + $13.07 = $82.72 This is how much she spent. If you add $7.28 to the grand total you will get how much she came in with... 82.72 + 7.28 = $90

  2. The amount of money Jenny came into the store with $90. I know this because if each t-shirt costs $9.95 and Jenny bought seven t-shirts, you would times 9.95x7= 69.65. Therefore, Jenny spent $69.65 on t-shirts. It also said that the cashier charged her $13.07 in sales taxes. So you take that $13.07 and add it with the previous $69.65 to make $82.72. So Jenny spent $82.72 but it says that she left with $7.28, so you add 7.28 to 82.72 to get 90.00. Therefore my answer is $90.

  3. She came into the store with $90 because 9.95x7 is 69.95+13.07=18.72 and then that has 7.28 left out of 9 so it is 90

  4. In total she spent$90. what i did was $9.95X7 becuase ach T-shirt is $9.95 and she bought one for each of her 7 brothers. that gives a total of: $69.65. then it said the taxes were: $13.07, so $13.07+ the total: $69.65= $82.72. the it said that she still had $7.28 after her shopping, so 82.72+$7.28= $90 as a total.

  5. At the beggining Jenny has 90$. I know this because she buys 7 shirts that cost $9.95 each. So, 7x9.5. You get $69.65. Then, taxes were $13.07. Now, it adds up to $82.72. After that, you have to add $7.28 because that is the amount she had afterwards. So, $82.72 (the cost of the shirts and taxes)+ 7.28 (what she had left over)brings you to a grand total of $90. And thats how i got my answer.

  6. she had $90 when she came into the store.
    9.95x7=$69.65+$13.07=$82.72 than you add in the $7.28=$90.

  7. Jenny started with $90. I first multiplied $9.95 X 7 = $69.65, the cost of shirts. Then I added $13.07 + $69.65, that = $82.72. $82.72 + $7.28= $90.

    The sales tax is way too high

  8. For this math question you have to do $9.95x7=$69.65+$13.07=$82.72+$7.28=$90.00 is how much she had to start of with.

  9. Jenny started with $90
    I know this because $9.95x7=$69.65+$13.07=$82.72
    $82.72 is how much she spent so I added everything she had left ($7.28) which came to a total of $90

  10. Jenny orginally had $90. I figured it out by adding up all her purchases, the tax and the money she had left. Here is the equation: ($19.95 x 7) + $13.07 + $7.28 = $90. And that is the grand total.

  11. Jenny had $90 when she came into the shop. I know this because it said that she spent money on 7 shirts costing $9.95 each so I did $9.95 x 7=$69.65. Therefore she spent $69.65 on shirts. She also spent $13.07 on tax so you have to add it up $69.95 + $13.07= $82.72. It also said that she had $7.28 left so I added $82.72 and $7.28 and it equaled $90.

  12. Jenny had $90 in total when she came into the shop. She paid $69.65 for the t-shirts. I know this because she bought 7 t-shirts, and 7x$9.95=$69.65. Then she was charged an extra $13.07, and $69.65+$13.07=$82.72. Finally, she walked out of the store with $7.28, so $69.65+$13.07+$7.28=$90.00. Therefore, Jenny walked out of the store

  13. Jenny had $90 to start off with. I know because she bought 7 $9.95 shirts. So I did 7 x $9.95 which equaled $69.65. Then there was the sales tax of $13.07 so I added that to $69.65 which gave it a total of $82.72. She had $7.28 left after she bought everything so add that to get your total $82.72 + $7.82= $90! that is how I got my answer

  14. In the beggining, Jenny had 90$. I know this because she bought 7 shirts at 9.95$. So, 7x9.95=69.65. Then, you have to add the tax which is 13.07, so you add 69.65+13.07=82.72. Then you have to add 7.28 which is what she had left after she had bought the t-shirts and it added up to 90$.so, So, thats how i got my answers

  15. Jenny came into the with 90$. I know this becuase she has seven brothers and all of them need a shirt(unless shes mean im not going to factor that in) so thats 7x9.95 and that equals 69.65$. Now you need to put the tax ontop of that so 69.65+13.07=82.72. Now i add how much she has left (7.28$)and that equals 90$.

  17. Jenny started out with $90, and i know this because she has 7 brothers, a t-shirt for each of them, costing $9.95 each shirt, = $69.3 (7 x 9.95) plus the sales tax, (plus $13.07) = $82.37, plus how much she ended with ($7.28) = $90.

  18. To determine the money she started with you do:9.95 x 7 (t-shirts) and add 13.07 (sales tax) and add 7.28 (change) to get $90!
