Question

You and your friend, each earn (14h+5c) dollars for washing H houses and see cars. Last month you washed 10 houses and your friend washed 28 cars. Who earned more money?

Answer 1

To determine who earned more money between you and your friend, substitute the number of houses and cars washed into the earnings expression to find out the respective earnings. Both you and your friend earned the same amount of money, which is 140 dollars.

Step-by-step explanation:

To determine who earned more money, we need to compare the earnings of both you and your friend.

You earned (14h+5c) dollars for washing H houses, and your friend earned (14h+5c) dollars for washing 28 cars.

Since we know that you washed 10 houses and your friend washed 28 cars, we can substitute these values into the earnings expression to find out the respective earnings.

1. For you: Earnings = (14h + 5c) * Number of houses = (14 * 10 + 5 * 0) = 140 dollars
2. For your friend: Earnings = (14h + 5c) * Number of cars = (14 * 0 + 5 * 28) = 140 dollars

Both you and your friend earned the same amount of money, which is 140 dollars.
