Assessment Practice

Answer: $7.72

Step-by-step explanation:

A easy way to this is by breaking each set of coins into values of 100 which we know is a dollar.

so 342 pennies can be divided into 100 3 times with the remainder of 42 cents so that $3.42

with nickels because they are worth 5 cents we have to see what times 5 = 100 which is 20. 62 goes into 20 3 times with the remainder of 2 and 2*5=10

so $3.10

dimes are worth 10 cents each so what times 10=100? 10 so 12 goes into 10 1 time with the remainder of 2 2*10=20 so $1.20

Then we add all the money $1.20+3.10+3.42=$7.72
