How many dollars do you have if you have 90 nickels, 16 dimes, 16 quarters, and 7 fifty-cent pieces? Show your work and explain each step.

$13.60

Step By Step:

A nickle is worth 5 cents.

A dime is worth 10 cents.

A quarter is worth 25 cents.

5 Cents • 90 Nickles = 450

10 Cents • 16 Dimes = 160

25 Cents • 16 Quarters = 400

50 Cents • 7 fifty-cent pieces = 350

450 + 160 + 400 + 350 = 1360

A dollar is worth 100 cents.

1360 ÷ 100 = $13.60

Step-by-step explanation:

You have 90 nickels

Since 20 nickels = 1 dollar you have 4 dollars and 10 nickels left over

The ten nickels left = 1/2 a dollar or 50 C

You have 16 dimes

10 dimes = 1 dollar

You have 1 dollar and 6 dimes left over.

So you have 1 dollar and 60 C

You have 16 quarters.

4 Quarters = 1 dollar

16/4 = 4 dollars. No quarters are left over.

You have 7 fifty-cent pieces

2 fifty cent pieces = 1 dollar

7/2 = 3 dollars and 50 cents left over.

I don't exactly know what you want as a final answer, but here is what I think it is

nickels =                     4 dollars and 50 cents

dimes   =                     1 dollar and   60 cents

quarters                      4 dollars

fifty cent pieces          3 dollars        50 cents

Adjustments                 1                     60 cents*

Totals                           13                    60 cents.

*The adjustment comes from 2 values of 50 cents each and 60 cents which cannot be combined with anything.

1/4 because there is 4 grades.
