Studio fee:$8 per hour <br> Vase:$10
aleksandrvk [35]

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.
