Karen bought a new sweater for 20% off the original price. If the original price was $49.99 and sales tax is 5.5%, how much did Karen spend on her new sweater?

Answer: First you need to find the actual cost of the sweater (original price minus the 20% off). Take $49.99 x .2 which equals $9.99. $49.99 - $9.99= $40.00 (cost of sweater on sale). Second you need to calculate sales tax (5.5%) on $40.00. Take $40.00 x .055 which equals $2.20.

Finally, you need to add the cost of the sweater, $40.00, and the cost of the sales tax, $2.20 together. $40.00 + $2.20 = $42.20

The answer is $42.20.
