Answer:

15 dimes

17 nickels

Step-by-step explanation:

Use a system of equations for this

n is nickels

d is dimes

n + d = 32

.05n + .10d = 2.35

solve first equation for n and plug this in the second equation

n = 32 - d

.05(32-d) + .10d = 2.35

1.6 - .05d +.10d = 2.35

1.6 + .05d = 2.35

.05d = .75

d = 15

n + 15 = 32

n = 17
