Frank has 24 pennies, 62 nickels, 55 dimes, 16 quarters, and 19 fifty-cent pieces. How much money does he have?
DedPeter [7]

Answer:

$22.34

Step-by-step explanation:

really simple.

just multiply the number by how much the coin is worth

24 x 1 = 24

62 x 5 = 310

55 x 10 = 550

16 x 25 = 400

19 x 50 = 950

then add all of them

24 + 310 + 550 + 400 + 950 = 2234

and finally divide it by 100

2234 ÷ 100 = 22.34

and just pop in a dollar sign
