Describe how you solved the following problem:

I have a jar filled with $100 worth of quarters, nickels, and dimes.

I have the same amount of each type of coin. How many total coins do I have in my jar?

First you make sure you have all your variables using same measurement - cents (since it is the smallest)

$100 = 100*100 cents = 100,000 cents

1 quarter = 25 cents

1 nickel = 5 cent

1 dime = 10 cents

the test of your problem said that:

you have $100 in i don't know how many coins of quarters, nickels and dimes

100,000 = X * (25+5+10)

we have to find X:

100,000 = X * (25+5+10)

100,000 = X * 40

X = 100,000/40

X = 2,500 coins
