Answer:
Let the cost of one apple pie be A and the cost of one blackberry pie be B.
From the first statement, we can write the equation:
SA + 4B = 8140 ----(1)
From the second statement, we can write the equation:
4*B = 152
Solving for B:
B = 38
Substituting B in equation (1) and solving for A:
SA + 438 = 8140
S*A = 8008
A = 8008/S
We do not have enough information to find the value of S or A individually, but we can find the relationship between them:
A/B = (8008/S)/38 = 211/S
Therefore, the cost of one apple pie is 211 times the cost of one blackberry pie.
