A dance instructor earns $75 for teaching 3 classes. The instructor receives a 10percent raise Enter how much the instructor earns, in dollars, per class after the raise.

$27.50

Step-by-step explanation:

3 classes=$75.00 10/100×75/1=$7.5 total for class is 75.00+7.5=82.5 per class=82.5÷3=27.5

$27.50

Step-by-step explanation:

First, we find what 10% of $75.00. Easiest way to do that is to move the decimal over one place to the left:

75.00 ⇒ 7.500 ⇒ 7.50

So the instructor would get a 7.50 raise added to her pay:

75.00 + 7.50 = 82.50

Finally, we divide 82.50 by 3 for each dance class:

82.50 ÷ 3 = 27.50

And there is your answer! The instructor would get $27.50 per class after their raise.

Hope this helps!

answer: c i think

step-by-step explanation:

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
