Question

Oliver owns a food truck that sells tacos and burritos. He only has enough supplies to make 110 tacos or burritos. He sells each taco for $4 and each burrito for $7.75. Oliver must sell a minimum of $620 worth of tacos and burritos each day. If 

x

x represents the number of tacos sold and 

Answer 1

4x+7.75y=620

x+y=110

x=62

y=48

Answer 2

x+y=110

4x+ 7.75y = 620

4x + 7.75(110 - x) = 620

4x + 852.5 - 7.75x = 620

-3.75x + 852.5 = 620

-3.75x = 232.50

x=62

y = 48

62 tacos and 48 burritos
