Question

Bart's Boats: $4 for a life jacket rental $5 per hour for boat rental Bike Land: Free life jacket rental $6 per hour for boat rental Let the y represent the cost, in dollars. Let x represent the number of hours. Write a system of equations for this situation.

Answer 1

y =4+5 x

y= 6x

Explanation:

Hi, to answer this question we have to write an equation for each case.

For Bart´s boats total cost (y) we have to sum the cost of the life jacket rental ($4) and the cost per hour for boat multiplied by the number hours ($5x)

Bart's boats: y =4+5 x

Where:

• y = total cost in $
• x = number of hours

Same process for bike land, since the jacket rental is free, it costs $0 .

Bike Land: y= 0+6x

The system of equations that represents this situation is:

y =4+5 x

y= 6x
