Question

We have $56 to spend on pizza and drinks. Pizza costs $12 each and drinks cost $0.50 each. Four times as many drinks as pizzas are needed. How many pizzas and how many drinks can we afford to buy?

Answer 1

12p+4p/2 =12p+2p=14p

=56

p=56/14=4 pizzas cost 4x12= $48

d=4p=4x4= 16 drinks costing 16x.5 = $8

48+8= $56

4 pizzas and 16 drinks
