thanks!

Answer 3

would you like me to explain why?

Answer 4

yeah

Answer 5

No? okie

Answer 6

oh okay

Answer 7

the reason why the answer is A is because in order to find out how much money she needs to save, you need to get the variable (n) alone. N stands for the money needed. you need to isolate n by subtracting 19 from both sides, the equation being:

n + 19 = 65
- 19 - 19

n = 46

at this point, you're left with: money needed to buy shoes = $46
