Question

A new sidewalk will be 4 feet wide and 50 yards long. Eighty pounds of concrete mix covers 4 square feet and costs $3.65. How much will the concrete for the new sidewalk cost?

Answer 1

50 yards=150 feet

4x150= 600 feet^2

600/80=7.5

7.5 x $3.65 =$27.375

Therefore it will be $27.375 for the concrete on the new sidewalk
