A shirt shop has 112 orders for T-shirt designs. Three designers can make 12 shirts in 2 hours. How many designers are needed to complete the orders in 8 hours?

Question

The main thing is to find the answer of course, and you have to use subgoals. The main thing also is to see how many designers are needed to complete the orders in 8 hours. You solve it using a solving strategy and by making it into a simpler problem first, than figuring the rest out. Sorry if this doesn't help, hehe.

Answer 1

So we need 112 orders and we have 8 hours. This means we need to complete 14(112/8=14) shirts per hour. If 3 designers can make 12 shirts in 2 hours, then they can make 6 shirts in 1 hour.

 

14shirts/hr*3workers/6shirts=7 workers/hour needed.
