Frank paid 5% sales tax on his television, which cost $769 before taxes. what did the television cost in total?

The television costs $769 dollars, but we want to add a 5% sales tax.

To convert a percentage to a decimal, we remove the percent sign and move the decimal point two places to the left.

5.0% = 0.05 

Therefore, to find the added amount of money that Frank will be taxed for buying the TV, we must multiply the percentage (decimal equivalent) by the total cost of the TV.

Thus, our expression would be 

0.05 * 769 = 38.45

However, this is the tax amount, and it is asking for the TOTAL cost.  To find this, we add the regular price to the tax price.

769 + 38.45 = 807.45

Frank's television cost $807.45 in total.

You would have 15$ left
