Kyle is renting a jet ski for the day. below are his two options. powersports plus: $30 an hour plus a non-refundable deposit of $50. sun & surf: $20 an hour plus a non-refundable deposit of $80. first, write an expression to show how to calculate the cost of powersports plus. then, write an expression to show how to calculate the cost of sun & surf. next, set the 2 expressions equal to each other. last, solve how many hours will the two companies cost kyle the same amount of money?

Lets x = # of hours

Powersports Plus: $30 an hour plus a non-refundable deposit of $50.

Write an expression to show how to calculate the cost of Powersports Plus.

30x + 50

Sun & Surf: $20 an hour plus a non-refundable deposit of $80.

Write an expression to show how to calculate the cost of Sun & Surf.

20x + 80

Next, set the 2 expressions equal to each other.

30x + 50 = 20x + 80

Solve:

30x + 50 = 20x + 80

        10x = 30

          x = 3

Two companies cost Kyle the same amount of money at 3 hours

the answer is n

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
