75 basketballs cost $1,143.75. Find the cost of 26 basketballs.

A. $ 396.50

B. $ 346.50

C. $ 333.50

D. $ 426.50

Answer : A. $ 396.50


Explanation:


    This is a situation of direct variation.

    Because, less number of basket balls —–> cost will be less.
    Given :
    75 basketballs cost = $1,143.75.
    Cost of one basket ball = 1143.75 / 75 = 15.25
    Then, cost of 26 basket balls = 15.25 x 26 = 396.50.
    Hence, the cost of 26 basket balls is $ 396.50.
