Answer:answer y = 337.5

Explanation:

y varies directly with x, so y = kx , where k is some constant.

y = kx When y = 75 , x = 1/2 . So

75 = k(1/2) Multiply both sides by 2 .

150 = k

y = 150x

To find y when x = 2 , plug in 2 for x .

y = 150( 2 ) 1/4 = 0.25 , so 2 + 1/4 = 2.25

y = 150( 2.25 )

y = 337.5
