Question

Studio fee:$8 per hour
Vase:$10

Answer 1

Answer:

4.5 hours

Step-by-step explanation:

So, let's write a function p(x) which represents the total cost.

Let's let x represent the amount of hours.

The cost of a piece is a constant 10.

And there is a $8 fee per hour. In other words:

$p(x)=8x+10$

We spent a total of $46.

So, substitute in 46 for p(x) and solve for x:

$46=8x+10$

Subtract 10 from both sides:

$36=8x$

Divide both sides by 8:

$x=36/8$

Reduce:

$x=4.5$

So, we spent about 4.5 hours.
