To solve this problem you must apply the proccedure shown below: 1. You have that Morgan can paint the house in about 5 days. Therefore, his rate is: rate=1/5 2. Then the rate that the two assistants must work for Morgan to meet a deadline of two days is: 2(1/5)+x(2)=1 2/5+2x=1 2x=1-(2/5) 2x=3/5 x=3/(5x2) x=3/10 The answer is: 3/10
