it costs $9 to go to Pete's Pottery place to paint custom bowls at a cost of $3 per bowl. Natalie plans to paint bowls 5 days this month and to paint b bowls on each day so she can sell them at a craft fair. which equation represents Natalie's total vost c for the month? C=5(3b+9)C=3(5b+9)C=5(9b+3)C=3(9b+5)

We know that it cost $9 to go to the pottery place. This is independent of the number of bowls painted.

Then, we know that she have a fixed cost of $9 per day.

We know that each bowl she paints will cost her $3.

Then, we know that she has a variable cost of $3 per bowl.

If she is expected to paint "b" bowls per day, she will have a cost-per-day that is the addition of the fixed $9 and the cost-per-bowl ($3 * b).

Then, she has a (9+3b) dollars per day.

If she is planning to attend 5 days, so the cost is:

C=5 * Cost-per-day = 5*(9+3b) = 5(3b+9)

The total cost for Natalie is 5(3b+9)
