Step-by-step explanation:

$2.77 per bar sold

Step-by-step explanation:

Hi there!

We're given that selling 9 ice cream bars could make the truck driver $24.93. To find how much he'd make per bar sold, divide $24.93 by 9 ice cream bars:

24.93 ÷ 9 = 2.77

Therefore, the truck driver would make $2.77 per bar sold.

We could also find this answer using the given equation, y=kx.

y=kx

Let y equal the earnings. Let x equal the number of ice cream bars sold. Let k equal how much the driver would make per bar sold.

24.93=k(9)

24.93=9k

x=2.77

I hope this helps!
