Lizzy: Jacob is building ladders. One of his clients needs 10 ladders with 50 rungs, and 20 ladders with 60 rungs. Jacob has to charge $2 for every rung. How much does the client have to pay for the ladders?.
Me: Hmmm, let me think. I think this is the detailed solution:
User
10 ladders with 50 rungs have a total of 10 * 50 = 500 rungs. 20 ladders with 60 rungs have a total of 20 * 60 = 1200 rungs. In total there are 1200 + 500 = 1700 rungs. The client must pay 2 * 1700 = $3400. Final answer: 3400.
