Here, let me consider Number of Apple Pies=X1
Number of Grape Pies=X2
They want to Maximize the sales Revenue, hence, Maximize Objective function=1.40*X1+1.25*X2
Constraints:
Sugar: 1.5*X1+2*X2=<1150
Flour: 3*X1+3*X2=<1800
8*X1+2*X2=<2700
X1 and X2>=0
Here, I will use graphical method to calculate the value of X1 and X2
Number of Apple Pies=250 pieces
Number of Grape Pies=350 pieces
Maximize the sales Revenue =1575/2=$787.5
Sugar=1.5*X1+2*X2=(1.5*250)+(2*350)=1075 cups
Flour=3*X1+3*X2=(3*250)+(3*350)=1800 Cups
Time=8*X1+2*X2=(8*250)+(2*350)=2700 Minutes
