It costs $.10 to print one page. Jenny wants to print 7 copies of her 25-page essay. She also wants to buy 7 pens that each cost $1.50. If she pays the store with 2 twenty dollar bills, how much money should she get in change?
How many pages does Jenny need to print? ** Jenny needs to print 7*25= <<7*25=175>>175 pages.
How much will it cost to print 175 pages? ** This will cost 175*$.10 =$<<175*.10=17.5>>17.5.
How much will the pens cost? ** The pens will cost 7*$1.50=$<<7*1.5=10.50>>10.50.
How much will Jenny spend in total? ** In total, she will spend $17.5+$10.5=$<<17.5+10.5=28>>28.
How much money does Jenny pay with? ** Since she pays with 2 twenty dollar bills she pays with 2*20=<<2*20=40>>40 dollars.
How much money should Jenny get in change? ** Thus, she will get $40-$28=$<<40-28=12>>12 in change.
