Question

Jerry sells doghouses at the city fair. Complete the rate chart below to find how much Jerry earns for selling a certain number of doghouses.

Answer 1

We can see in the table, on the top row, that the number of doghouses sold increases by 4 each column. When he sold 8 doghouses, he earned 40. When he sold 12 houses, he earned 60. This means that he earns $20 for every 4 doghouses sold.

If he earned $100 for selling 20 houses, if he sells 24 he will earn:

`100+20=120`

Thus, the answer is option B. 120
