Answer:
400
Explanation:
A quarter is worth 0.25, so 4 quarters equals 1 dollar
0.25+0.25+0.25+0.25=1
So, there are 4 quarters in a dollar, 8 quarters in 2 dollars, 12 in 3 dollars, etc
So, we know that we can just multiply the dollar amount by 4 to find the number of quarters
100*4=400
So, there are 400 quarters in $100
Hope this helps! :)
