Question

Sliced turkey costs $3.20 per pound. roast beef costs twice as much, and ground beef costs half as much as the turkey. the science club ordered 5 pounds of each for its annual picnic. what was the total cost?

Answer 1

slice turkey (S)= 3.20 per pound
Roast beef(R)= 2×S= 2×3.2 =6.4
ground beef(g)=0.5× S =0.5×3.2= 1.6
total cost= 5×S+5×R+5×g
=5×3.2+ 5×6.4 + 5×1.6=56
thus, total cost is $56
