Question

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

Answer 1

5 lb of turkey = 5 x 3.20 = 16.00

 

 

1 lb of roast beef = twice as much as 1 lb turkey = 2 x 3.20 = 6.4

5lb of roast beef = 5 x 6.40 = 32.00

 

1 lb of ground beef = 1/2 as much as turkey = .5 x 3.20 - 1.60

5lb ground beef = 5 x 1.60 = 8.00

 

Total cost of 5 lb of each meat = 16.00 + 32.00 + 8.00 = 56.00
