mrs. brittle is planning a party for all students who get a level 3 or 4 on math test.using a total of $112.00 she plans to get a pizza that costs $12.00 each and drinks that $0.50 each. if she purchases four times as many as pizzas how many of each should she buy ?

p = 4 d

112 = 12 p + .5 d

d = 2.31
p = 111

I am sure you have this backwards
