--------------------------
Quantity Equation: a + p = 21
Value Equation::: 15a+20p = 380 cents
-------------------------------------------
Multiply thru top equation by 3
Divide thru bottom equation by 5
------
3a + 3p = 63
3a + 4p = 76
-----
Subtract and solve for "p":
p = 13 (# of pears)
------
Solve for "a" using a + p = 21
a + 13 = 21
a = 8 (# of apples)
