Consider the Q and A. Q: 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?
A: 160
What is the step-by-step reasoning process?
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.

Consider the Q and A. Q: 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?
A: 6
What is the step-by-step reasoning process?
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.

Consider the Q and A. Q: Tom finds 10 quarters, 3 dimes, and 4 nickels and 200 pennies. In dollars, how much money did he find?
A: 5
What is the step-by-step reasoning process?
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.

Consider the Q and A. Q: 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?
A: 360
What is the step-by-step reasoning process?
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.
