An ice cream truck driver used the equation Y=KX to show how much money he made selling 9 ice cream bars. He determined he'd make $24.93. How much did he make per bar sold?

$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!

yes

yes yes yes

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
