Chet bought a sweater that was on sale for 30% off the regular price of $75.00. if a 6% sales tax was added to the sale price, what was the final cost of the sweater? a) $55.65 b) $79.50 c) $97.50 d) $111.30

Chet bought a sweater for 30% off.

That means he paid 70% because:

Find 70% of 75. First change 70% to a decimal.

To change a percent to a decimal, remove the percent sign and move the decimal point 2 places to the left.

Now multiply

There's a 6% sales tax. Find 6% of 52.50 and add it to 52.50.

Now multiply

Add that to $52.50.

Your answer is A) $55.65
