Charlie and Lucy run a woodworking shop. In a total of 12 days, they can build 10 rocking chairs. Lucy alone can make 10 rocking chairs in 30 days. How long would it take Charlie to make 10 rocking chairs?
Charlie's work rate is c. Lucy's work rate is l. 12 days of Charlie and Lucy working together making 10 rocking chairs is 12c + 12l = 10. 30 days of Lucy building 10 rocking chairs alone is 30l = 10 Solve for 30l = 10 ; 30/30l = 10/30 ; l = 1/3 If l = 1/3, plug that into the original equation of 12c + 12l = 10 12c + 12(1/3) = 10 ; 12c + 4 = 10 ; 12c = 6 ; 12c/12 = 6/12 ; c = 1/2 This means Charlie's rate is 1/2 a rocking chair a day, meaning he is faster than Lucy. It would take him 20 days to build 10 rocking chairs.
