I'll have a pizza and 2 drinks

Question

Jeff spent $12 for a pizza and two drinks. The pizza costs twice as much as the two drinks? How much did each item cost?

Answer 1

Hi Jeff,

 

each drink costs d

 

the pizza p costs 2 time 2d or 4d since it costs twice as much as the two drinks together

 

Everything costs p + 2d = 4d + 2d =$12,  ==> 6d = $12, or d = $2

 

Thus the drinks cost $2 each and the pizza cost $8.
