Melinda, zachary and heather went to the mall to shop for school supplies. melinda spent 14.25 on her supplies. zachary spent 2.30 more than melinda spent. heather spent 2 times as much money as zachary spent

Easy as pie!

first you have to know what each person has

melinda = 14.25

zachary has 2.30 more than melinda so, 14.25+2.30

zachary = 16.55

heather has spent 2 times as much as zachary, so 16.55 x 2

heather = 33.10 or 33.1

good luck!
