Answer:

$5.95
720 bu

Step-by-step explanation:

We assume the given ratios are proportional. I find it easiest to write the proportion with the unknown in the numerator.

a) dollars/ounces = x/17 = 7/20

Multiply by the inverse of the coefficient of x to solve.

x = 17(7/20) = 5.95 . . . dollars

b) bushels/acres = x/9.6 = 225/3

x = 9.6(225/3) = 720 . . . bushels
