Answer 1

Q = quarters
N = nickels
25Q + 5N = 1480
Q + N = 88
Solve using those equations

Answer 2

(quarters are worth 25 cents, nickels are 5 cents0

Answer 3

Answer 4

@StudyGurl14

Answer 5

um...no...Use the system of equations and solve for Q and N

Answer 6

25Q + 5N = 1480
Q + N = 88
Q = 88 - N
25(88-N)+5N = 1480
2200 - 25N + 5N = 1480
-20N = -720
N = 36

So..36 nickels

Can you do the rest?

Answer 7
