Answer:answer y = 337.5
Step-by-step 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
