Answer:

$63

Step-by-step explanation:

  • Penny = $0,01
  • Nickel = $0.05
  • Dime = $0.1
  • Quarter= $0.25
  • Number of pennies = 6*50 = 300
  • Number of nickels = 5*40= 200
  • Number of dimes = 4*50= 200
  • Number of quarters = 3*40 = 120

<u>Total amount of money:</u>

  • 300*0.01+ 200*0.05 + 200*0.1 + 120*0.25 = $63
