Question #342de

Answer 1

Let there be `x` quarters and `50-x` pennies in the total 50 coins collected in the piggy bank.The total being `$9.62` or 962 cents.

Now

`x" quarters"=25x" cents"`

`(50-x)" pennies"=(50-x)" cents"`

So we can write

`x*25+50-x=962`

`=>24x=962-50=912`

`=>x=912/24=38`

So there are 38 quarters and 12 pennies.
