A:Let’s first figure out how many pennies are in a dollar. This will make it easy to determine how many pennies are in 100 dollars.
A penny is worth 1 cent. You will have to collect 100 pennies to equal a dollar. Since there are 100 pennies in one dollar, you can find out how many pennies are in 100 dollars by multiplying the 100 pennies by 100 as follows:
100 pennies x 100 = 10,000 pennies
There are 10,000 pennies in 100 dollars.
