Step-by-step explanation:
The volume of a triangular pyramid can be found using the following formula:

Basically, we have to multiply 1/3, the height, and the base area.
We know that the base area is 8.2 square centimeters and the height is 4 centimeters.

Substitute the values into the formula.

Multiply 8.2 square centimeters and 4 centimeters.

Multiply 1/3 and 32.8 cubic centimeters.

Round to the nearest tenth.
The 3 in the hundredth place tells us to leave the 9 in the tenth place.

The volume of the triangle pyramid is about 10.9 cubic centimeters.
So we know $8.50 per hour
One-time fee of $15 for uniform
x hours per week
y=8.5x-15
