Susan loves chairs. In her house there are red chairs, yellow chairs, and blue chairs. There are 5 red chairs. There are 4 times as many yellow chairs as red chairs, and there are 2 fewer blue chairs than yellow chairs. How many chairs are there in Susan's house? Let's be accurate as possible.
The number of yellow chairs is 5 chairs × 4 = 20 chairs. The number of blue chairs is 20 chairs − 2 chairs = 18 chairs. There are 5 chairs + 20 chairs + 18 chairs = 43 chairs in Susan's house.
The answer: 43.
