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!

Step-by-step explanation:

This is how you would proceed:

Centered at D, draw an arc of 7m (3.5cm) within the garden (rectangle).

Centered at B, draw an arc of 4m (2cm) within the garden.

There will be two intersection points, one is outside the garden (that you will not see), and the other is within the garden, which is where the tree should be planted.
