Answer :
First, found out how many coins are pennies and subtract that from the first 220. Note 40% is .40 times the amount
220 * .40 = 88 pennies
220 - 88 = 132 other coins
Of these remaining 132 coins 25% are quarters, so calculate this to find the answer:
132 * .25 = 33 quarters!
220 * .40 = 88 pennies
220 - 88 = 132 other coins
Of these remaining 132 coins 25% are quarters, so calculate this to find the answer:
132 * .25 = 33 quarters!
Answer:
33 quarters
Step-by-step explanation:
Given,
Total number of coins = 220,
Of those 40% are pennies,
So, the coin that are pennies = 40% of 220
[tex]=\frac{40\times 220}{100}[/tex]
[tex]=\frac{8800}{100}[/tex]
= 88
Thus, the number of coins which are not pennies = 220 - 88 = 132,
Now, Out of the coins that are not pennies, 25% are quarters,
Hence, the number of quarters = 25% of 132
[tex]=\frac{25\times 132}{100}[/tex]
[tex]=\frac{132}{4}[/tex]
= 33.
