Mr. McNeil bought two magazines for 7.45 and one book for 14.95. If the sales tax is 6%, what is the total cost of Mr. McNeil's purchase?

total cost = $22.4 + $1.12 = $23.52

Step-by-step explanation:

Mr McNeil bought 2 magazines for $7.45 and 1 book for $14.95. The sales tax is 6%. The total cost of Mr McNeil can be calculated as follows.

He bought 2 magazines for $7.45. This means the sum of the prize of the 2 magazine he bought is $7.45 and the prize for the single book he bought is $14.95. The total cost of the items he bought excluding the sales tax is the sum of the whole items he bought.

total cost excluding sales tax = $7.45 + 14.95 = $22.4

The sales tax is 5% which can be calculated as follows

5/100 * 22.4 = 112/100 = $1.12

The total cost of Mr McNeil purchase including his sales tax is

total cost = $22.4 + $1.12 = $23.52
