If a label states that 1 mil contains 500 mg, how many mils are there if there are 1.5 grams?
- A. 2
- B. 5
- C. 9
- D. 3
Correct Answer: D
Rationale: To convert grams to mils using the given conversion rate of 1 mil = 500 mg, you need to first convert grams to milligrams. Since 1 gram = 1000 milligrams, 1.5 grams would be 1500 milligrams. To find out how many mils this corresponds to, you divide the total milligrams by the milligrams per mil: 1500 mg · 500 mg/mil = 3 mils. Therefore, the correct answer is 3.

A man wants to get the best deal he can for gasoline, so he travels out of his way to buy gas at $2.14 a gallon instead of $2.26, which is the price at his local station. If he put 15.7 gallons in his tank, how much did he save by going to the less expensive station?
- A. $1.88
- B. $5.03
- C. $0.12
- D. $18.00
Correct Answer: A
Rationale: The correct answer is A: $1.88. To calculate the savings, we subtract the cost of gas at the local station ($2.26/gallon) from the cheaper station ($2.14/gallon): $2.26 - $2.14 = $0.12 saved per gallon. Multiply the savings per gallon by the total gallons purchased (15.7 gallons): $0.12/gallon x 15.7 gallons = $1.88 saved.
Choice B ($5.03) is incorrect as it is not the result of the correct calculation. Choice C ($0.12) is also incorrect as it represents the savings per gallon, not the total savings. Choice D ($18.00) is incorrect as it does not align with the actual savings achieved by purchasing at the cheaper station.

After spending $75.64 at one store and $22.43 at the next store, how much money does a shopper who started with $100.00 have left?
- A. $1.93
