9514 1404 393

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
