Dad’s truck is 15 feet long. The trailer it tows is 40% longer the truck. How long the trailer?

elena-14-01-66 [18.8K]

Answer:

21 Feet Long

Step-by-step explanation:

You just reverse how you find a percentage.

1) 40 / 100 = .40

2) .40 * 15 = 6

3) 6 + 15 = 21

I did it this way because I need to find what 40% is to 15. But the trailer isn't 40% of the truck, it's 40% longer than the truck. So, we must add those 2 numbers together getting 21 Ft.
