Question:

Shaylee goes shopping for two types of fruit: mangoes that cost $2.00 each and coconuts that cost $4.00 each. If she buys 10 pieces of fruit and spends $30.00, how many pieces of each type of fruit did she buy?

A
5 mangoes and 5 coconuts

Explaination

If mangoes are represented by x and coconuts are represented by y, then:

x + y = 10, and 2x + 4y = 30

2(10-y) + 4y = 30

20 – 2y + 4y = 30 2y = 10

y = 5 and x = 5, or 5 of each type of fruit.
