Dana is shopping for clothes, she wants to buy a pair of shorts for $12 and plans to spend the rest on $7.50 tank tops. How many tank tops can she buy if she wants to spend less than $42?

3 tank tops

Step-by-step explanation:

12 + 7.50 = $19.5

If you add 2 more of the 7.50 you will get

34.5

so she will have enough for 3 tank tops if she doesn't want to buy 4 which would be $42.

is this part of a question or something

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
