Question

The sales tax in one town is 8%. So, the total cost of an item can be written as c+0.08c. What is the total cost of an item that sells for 12?

Answer 1

12.96c

Explanation:

Given the total cost of an item written as c+0.08c. To get the total cost of an item that sells for 12, we will write;

1 item = c+0.08c

1 item = 1.08c

For 12items;

12 = x

Divide both expressions

1/12 = 1.08c/x

1 * x = 12 * 1.08c

x= 12.96c

Hence the total cost of 212 items is 12.96c
