Question 1 of 5
Tamison bought 20 stamps for 29¢ each and 40 stamps for 42¢ each. If she gave the postal worker $25, how much change did she receive?
Correct Answer: A
Rationale: First, calculate the total cost of the 20 stamps bought at 29¢ each: 20 stamps * 29¢ = $5.80. Next, calculate the total cost of the 40 stamps bought at 42¢ each: 40 stamps * 42¢ = $16.80. The total cost of all stamps is $5.80 + $16.80 = $22.60. If Tamison gave $25 to the postal worker, her change is $25 - $22.60 = $2.40. Therefore, the correct answer is A. Option B, C, and D are incorrect as they do not reflect the correct change Tamison received after buying the stamps.
Question 2 of 5
Teresa began collecting baseball cards exactly 8 months ago, and in that time, she has collected 144 cards. On average, how many baseball cards has she collected per month?
Correct Answer: C
Rationale: Teresa collected 144 baseball cards in 8 months. To find the average number of cards collected per month, we divide the total number of cards by the total months: 144 cards · 8 months = 18 cards per month. Therefore, on average, Teresa has collected 18 baseball cards per month. Choice A (12), Choice B (16), and Choice D (22) are incorrect as they do not match the correct calculation based on the information provided in the question.
Question 3 of 5
What is 70% of 110?
Correct Answer: C
Rationale: In this question, we are asked to find 70% of 110. To calculate this, we multiply 110 by 0.70 (which is the decimal form of 70%). So, 110 x 0.70 = 77. Therefore, the correct answer is A) 77. Let's analyze why the other options are incorrect: - B) 79: This is not correct because 79 is not the result of finding 70% of 110. - C) 81: This is not correct as well, as 81 is not the correct calculation for 70% of 110. - D) 83: Similarly, this answer is incorrect as it does not represent 70% of 110. Educationally, understanding how to calculate percentages is crucial in various fields, including pharmacology. Being able to determine percentages accurately is essential for dosage calculations, drug concentrations, and many other pharmaceutical calculations. This math skill ensures precision and accuracy in medication administration, which is vital for patient safety and effective healthcare delivery.
Question 4 of 5
Divide: 5,117 · 31 =
Correct Answer: D
Rationale: When dividing 5,117 by 31, the quotient is 165 with a remainder of 2. The correct answer is 165 r2. Choices A, B, and C are incorrect as they do not reflect the correct division result. Choice A is close but has the wrong remainder. Choices B and C have incorrect quotients and remainders, making them inaccurate. Therefore, the correct answer is D, 165 r2.
Question 5 of 5
Gus is making a chili recipe that calls for three parts beans to five parts ground beef. If he is using 8 cups of ground beef for a big family dinner, how many cups of beans will Gus need?
Correct Answer: B
Rationale: For every 3 parts of beans, Gus needs 5 parts of ground beef. This means the ratio of beans to beef is 3:5. If Gus is using 8 cups of ground beef, the total parts would be 3 parts beans to 5 parts beef, which is a total of 8 parts. To find out how many cups of beans Gus needs, we can set up a proportion: 3/5 = x/8. Cross multiplying gives us 5x = 24. Solving for x, we get x = 4. Therefore, Gus will need 4 cups of beans. Choice A, C, and D are incorrect as they do not align with the correct proportion calculation.
