6 0

Answer:

I got 358,800

Step-by-step explanation:

First you can choose from 26 letters, then from 25 (because you can't use the same letter) then from 24, and then from 23. You multiply 26 * 25 * 24 * 23 and you get your answer.

Jenna has at most $80 to spend on clothes. She wants to buy a pair of jeans for$22 and spend the rest on t-shirts. Each t-shirt

weqwewe [10]

Answer:

7 shirts

Step-by-step explanation:

You first have to subtract 22 from 80, since that's how much she already spent, 80-22=58. Now you have to do 58/8, but since 8 doesn't divide evenly into 58, you have to go with the closet multiple of 8 which would be 56. 7x8=56, so Jenna can buy a maximum number of 7 shirts.
