To rent a hall for a party reception (for 1 evening) costs $225. The Hall is also charging $25.50 per adult and $19.95 per child for the meal and reception. Gratuity is 15% of total costs. If 125 adults and 32 children attending the party, what is the total cost.... including gratuity?

Answer: Set up the problem as follows:

First part: (cost of hall + (cost of adult meal)(number of adults attending)+ (cost of child meal)(number of children attending)
Second part: 15% of (cost of hall + (cost of adult meal)(number of adults attending)+ (cost of child meal)(number of children attending)
.
Find the answers to part one and two, and then add them together.
.
Part one- hall and meals: $225 + (125 x $25.50) + (32 x $19.95) = $4050.90.
Part two- gratutity: .15 x $4050.90 = $607.34
.
Total cost: $4050.90 + $607.34 = $4658.24

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.
