Julien is buying donuts to bring to his aunt's house for breakfast. He wants to buy one donut for each of the 9 people attending, which includes himself. He buys some blueberry cake donuts, which cost $3 each, and some chocolate glazed donuts, which cost $2 each. If Julien spends $20 before tax, how many of each type of donut did he buy?

3B + 2C = 20

B + C = 9

B = 9 - C

3(9 - C) + 2C = 20

27 - 3C + 2C = 20

C = 7

B = 2

2 blueberry cake donuts

7 chocolate glazed donuts
