Question

Frenchie’s Tool rental charges customers $16 per hour to rent a riding lawnmower. Make a table of ordered pairs in which the x-coordinate (domain) represents the number of hours and the y-coordinate (range) represents the total cost of renting the lawnmower for 3, 7, 8, and 12 hours.

Answer 1

`\begin{array}{cc}x&y\\ \\3&48\\7&112\\8&128\\12&192\end{array}`

Explanation:

Let x represents the number of hours and y represents the total cost of renting the lawnmower.

Frenchie’s Tool rental charges customers $16 per hour to rent a riding lawnmower, then renting for x hours costs $16x, thus,

y=16x.

When x = 3, then
`y=16\cdot 3=48`

When x = 7, then
`y=16\cdot 7=112`

When x = 8, then
`y=16\cdot 8=128`

When x = 12, then
`y=16\cdot 12=192`

Therefore, the table is

`\begin{array}{cc}x&y\\ \\3&48\\7&112\\8&128\\12&192\end{array}`
