Four items are purchased at prices of: $5.30, $1.29, $.53 and $.68. Sales tax applies at 5% of the total purchase price. What is the total charge?

5.30 plus 1.29 plus 0.53 plus 0.68 equal 7.80$ times 0.5% tax 8.19$

Hence, the total charge = $ 8.19

Step-by-step explanation:

It is given that:

Four items are purchased at prices of: $5.30, $1.29, $.53 and $.68.

This means that the total cost of the purchase is:

$ (5.30+1.29+0.53+0.68) = $ 7.8

Also, the sales tax applied on it is:

5% of the total purchase price.

This means that:

Amount of tax = 5% of 7.8

= 0.05*7.8

= $ 0.39

The total charge = $ 7.8 + $ 0.39

Total charge = $ 8.19
