Paint costs $3.99 per can and brushes cost $2.50 each. the sales tax rate is 5%. which expression represents the total cost of p cans of paint and b paint brushes? a. 3.99p + 2.50b b. 0.05(3.99p + 2.50b) c. 1.05(3.99p + 2.50b) d. –1.05(3.99p + 2.50b)

C. 1.05(3.99p + 2.50b)

Step-by-step explanation:

Hi, to answer this question we have to write an inequality with the information given:

Paint can cost : 3.99

Brush cost : 2.50

Sale tax rate : 5% : 0.05 (decimal form, 5/100= 0.05)

So, to calculate the total cost, first, we have to multiply each cost by the quantity of each item.

3.99 p + 2.50 b

Where p is the number of paint cans and b is the number of brushes

Since we have to add the tax rate we have to multiply that expression by (1 +0.05) , the percent increase.

. 1.05(3.99p + 2.50b) (option C)

Feel free to ask for more if needed or if you did not understand something.
