Answer:
y = (500 + n)(10 - 0.01n)
Step-by-step explanation:
Let y = the yield of grapes per acre
and n = the number of vines.
y = number of vines × yield per vine
For each additional vine that is planted, the yield decreases by 1 % (0.01 n).
y = (500 + n)(10 - 0.01n)
The number of pounds of grapes produced per acre is modeled
by y = (500 + n)(10 - 0.01n).
