x_2=90 cubic feet of fertilizer is used in y_2=990 pounds of strawberries

x=72 cubic feet of fertilizer is used

Linear interpolation is applied

y=y_1+\dfrac{(x-x_1)(y_2-y_1)}{x_2-x_1}\\\Rightarrow y=770+\dfrac{(72-70)(990-770)}{90-70}\\\Rightarrow y=792\ \text{pounds}

72 cubic feet of fertilizer will yield 792\ \text{pounds} of strawberries.
