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.
