[Question]: Bret and a team of 3 co-workers were working late so he ordered dinner for everyone. They decided on Chinese. Each main meal costs $12.0. They also ordered 2 appetizers that were $6.00 each. He includes a 20% tip and an extra $5.00 to make it a rush order. How much does Bret spend on dinner?
[Answer]: There are 4 co - workers and each of their meals is $12.00 so 4 * 12 = $48.00. They order 2 appetizers at $6.00 each so 2 * 6 = $12.00. The meals costs $48.00 and the appetizers costs $12.00 for a total of 48 + 12 = $60.00. A 20% tip on the $60.00 order is .20 * 60 = $12.00. So the meal is $60.00, the tip is $12.00 and he adds a $5.00 rush for a total of 60 + 12 + 5 = $77.00.
So the answer is 77.

[Question]: Jim collects model cars, and he has 301 models total. Jim has 4 times as many Buicks as Fords, and 3 more than twice the number of Fords than Chevys. How many Buicks does Jim have?
[Answer]: Let x represent the number of Chevys. Fords:3 + 2x. Buicks:4(3 + 2x) = 12 + 8x. Total:x + 3 + 2x + 12 + 8x = 301. 11x + 15 = 301. 11x = 286. x = 26. Buicks:12 + 8(26) = 220.
So the answer is 220.

[Question]: John used to buy 4 coffees a day for $2 each. They raised the price by 50% so he cut the number of coffees he drinks in half. How much money does he save per day compared to what he used to spend?
[Answer]:
He now buys 4 / 2 = 2 coffees. The new price is 2 * .5 = $1 more than the old price. So he now pays 2 + 1 = $3 per coffee. So he spends 3 * 2 = $6. He used to spend 4 * 2 = $8. So he saves 8 - 6 = $2 per day.
So the answer is 2.
