Answer the following question.
Marc bought 5 model cars that cost $20 each and 5 bottles of paint that cost $10 each. He also bought 5 paintbrushes that cost $2 each. How much did Marc spend in total?
Step-by-step reasoning process: The 5 model cars cost $20 x 5 = $100. The 5 bottles of paint cost $10 x 5 = $50. The 5 paint brushes cost $2 x 5 = $10. Thus, Marc spent $100 + $50 + $10 = $160 in total.
The answer is 160.

Answer the following question.
The cost of a slice of cake is three-fourths of the cost of a cup of milk tea. If the milk tea costs $2.40, how much do 2 slices of cake and 1 cup of milk tea cost?
Step-by-step reasoning process: The cost of a slice of cake is $2.40 x 3 / 4 = $1.80. So, 2 slices of cake cost $1.80 x 2 = $3.60. Therefore, 2 slices of cake and 1 cup of milk tea cost $3.60 + $2.40 = $6.
The answer is 6.

Answer the following question.
Tom finds 10 quarters, 3 dimes, and 4 nickels and 200 pennies. In dollars, how much money did he find?
Step-by-step reasoning process: He found 10 * .25 = $2.5 in quarters. He found 3 * .1 = $.3 in dimes. He found 4 * .05 = $.2 in nickels. He found 200 * .01 = $2 in pennies. So in total, he found $2.5 + $0.3 + $0.2 + $2 = $5.
The answer is 5.

Answer the following question.
Tom uses 10 weight plates each weighing 30 pounds on an exercise machine. This exercise machine uses special technology to make the weights 20% heavier on the lowering portion. How heavy did the weights feel when being lowered?
Step-by-step reasoning process: The weight stack weighed 10 * 30 = 300 pounds. So the added weight made it 300 * .2 = 60 pounds heavier. So when he lowered the weight it was 300 + 60 = 360 pounds.
The answer is 360.
