Answer :
Task :
- To find the cost of each type of pie
Solution :
Let the peach pies be P and the apple ones be A.
ATQ,
Dylan sold 5P & 3A for $22.
The following can be written as
and,
Bailey sold 4P & 3A for $22 which can be also written as
Multiplying equation (1) by 4 and equation (2) by 3, we get,
- 12P + 20A = $88....(3)
- 12P + 9A = $66...(4)
Subtracting equation (4) from equation (3), we get,
- 11A = $22
- A = $22/11
- A = $2
Thus, the cost of each apple pie is $2.
Plugging in the value of A in equation (1),
- 3P + 5($2) = $22
- 3P + $10 = $22
- 3P = $22 - $10
- 3P = $12
- P = $12/3
- P = $4
Therefore,the cost of each peach pie is $4.
