Ben needs to choose between three brands of shingles to use on roof. he knows he needs 89 bundles of shingles but each type of shingle weighs a different amount. he needs to take the information he has about the cost of the crane and the amount it can lift to determine the cost of using each brand.
the crane cost $350 plus an additional $150 for each hour or part of an hour the crane is used. the crane can make 4 lifts in one hour. each lift must weigh 650 pounds or less. the weights of a bundle of each brand of shingle is a= 75, b=80 and c=85.
decide which brand of shingles should be choose. explain your reason.
number of bundles in one lift. number of lifts needed. number of hours needed and total cost of the crane for each brand.
