Question

Daniel decides that he wants to Kayak on Lake Travis. Go-Koyak charges $15 to rent the Kayak and $4 an hour for use. Fun Kayaking charges no fee to rent $6 an hour for use. After how many hours will Daniel have to Kayak for the two charges to be equal? Write an equation from the word problem and solve.

Answer 1

Answer: 7 hours 30 mins

Explanation:

1. Daniel needs to spend the same time in Go-Kayak, and Fun Kayaking in order for both charges to be equal. We will keep that amount of time as X.

2. Write it as an equation. 15 + 4x = 6x

3. Now, solve the equation. 15 = 2x. 15/2 = x

4. In other words, X is 15/2 hours, which is 7 hours and 30 mins.

Word Problem: 15 + 4x = 6x
