Ayana has 220 coins in her piggy bank. Of those 40% are pennies. Out of the coins that are not pennies, 25% are quarters. How many of the coins are quarters?"

Sagot :

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!

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.
