Answer:

  • 16 nickels

Step-by-step explanation:

Given

  • Nickel  n = 5 c
  • Quarter  q= 25 c
  • Total change = $3.80 = 380 c
  • n = q + 4

Solution

  • 5n + 25q = 380
  • 5(q + 4) + 25q = 380                        ⇒ substitute n with q + 4
  • 5q + 20 + 25q = 380
  • 30q = 360
  • q = 360/30
  • q = 12
  • n = q + 4 = 16

12 quarters

16 nickels
