Pedro goes to the market and buys a total of 32 plums and peaches for $52. A plum costs $2 and a peach costs $1. How many plums did Pedro buy?
-----
Quantity Equation: u + e = 32
Value Equation::: 2u + e = 52
---
Subtract and solve for "u":
u = 20 (# of plums)
---
Solve for "e":
u + e = 32
20 + e = 32
e = 12 (# of peaches)
