In a shopping mall, one T-shirt costs $20 each; a pair of pants costs $80; a pair of shoes costs $150. All items will get a 10% discount. How much does Eugene have to pay if he buys four T-shirts, three pairs of pants, and two pairs of shoes?
Let's think: The total cost of the four T - shirts is 4 x $20 = $80. Three pairs of pants cost 3 x $80 = $240. Two pairs of shoes cost 2 x $150 = $300. The total amount of all the items is $80 + $240 + $300 = $620. Thus, Eugene will get a discount of 10 / 100 x $620 = $62. Therefore, Eugene will have to pay $620 - $62 = $558.. The answer is: 558.

Matt can buy key chains in packs of 10 for $20 or in packs of 4 for $12. How much money can he save if he chooses to buy 20 key chains at a lower price?
Let's think: The cost of each key chain in packs of 10 for $20 is $20 / 10 = $2. The cost of each key chain in packs of 4 for $12 is $12 / 4 = $3. There is a price difference of $3 - $2 = $1 per key chain between the two choices. By buying 20 key chains at a lower price, Matt can save 20x$1 = $20.. The answer is: 20.

Robby doesn't like the color brown and will not eat the brown M&M's. On his first bag, he sets aside 9 brown M&M's. On the second bag, he sets aside 12. On his third & fourth bag, there are 8 brown M&M's that he doesn't eat. On his fifth bag, there are only 3 brown M&M's that he doesn't eat. What's the average number of brown M&M's in a bag?
Let's think: Out of 5 bags, he had 9 + 12 + 8 + 8 + 3 = 40 brown M&M's. He ate 5 bags so the average number of brown M&M's per bag was 40 / 5 = 8 brown M&M's.. The answer is: 8.

Andy works in the pro shop at a tennis resort, where he earns $9 an hour. In addition to this, he gets paid $15 for each racquet he restrings, $10 for changing out the grommets on a racquet, and $1 for painting a stencil on the racquet strings. How much does he earn (before taxes) during an 8-hour shift if he strings 7 racquets, changes 2 sets of grommets, and paints 5 stencils?

Andy works 8 hours, so he earns a wage of 8 hours * $9 per hour = $72 just for working there. During that time, he restrings 7 racquets, so he earns 7 racquets * $15 per racquet = $105 from stringing. He also changed the grommets in 2 of those racquets, so he earned 2 grommet jobs * $10 per grommet job = $20 from changing grommets. And he stenciled 5 racquets, so he earned 5 stencil jobs * $1 per stencil job = $5 for stenciling. In total, Andy earned $72 + $105 + $20 + 5 = $202 for the day.. The answer is: 202.
