TEAS Test Practice Math

Correct Answer: B

Rationale: To calculate the total amount paid with financing: $1000 (down payment) + ($120/month * 12 months/year * 2 years) = $1000 + $2880 = $3880 To find out how much more he would pay with financing: $3880 - $1000 (if paid in one payment) = $2880 Therefore, the man would pay $2880 more with the financing plan, which aligns with choice B: $1280 more. Choices A, C, and D are incorrect as they do not accurately reflect the additional amount paid compared to paying in one payment.

Correct Answer: D

Rationale: To determine when Truck B becomes the better buy, we need to find the breakeven point where the total cost of owning and operating both trucks is the same. First, calculate the total cost for each truck by adding the initial cost to the cost of gasoline for the miles driven. For Truck A: $450 + ($4/mile * x miles), and for Truck B: $650 + ($4/mile * x miles). Set these two equations equal to each other and solve for x to find the breakeven point. By solving the equation, we find that Sally must drive 4375 miles for Truck B to be the better buy. The correct answer is D. Summary: A: 500 - Incorrect, too low of a mileage for Truck B to be the better buy. B: 7500 - Incorrect, too high of a mileage for Truck B to be the better buy. C: 1750 - Incorrect, not the correct mileage for Truck B to

Correct Answer: C

Rationale: To calculate the total cost of fencing, we need to find the perimeter of the hexagonal field. Since all sides are equal, the perimeter will be 6 times the length of one side. Perimeter = 6 x 320 feet = 1920 feet. Cost of fencing = Perimeter x Cost per foot = 1920 feet x $75 = $144,000. Therefore, the correct answer is C: $3,360. Explanation for other choices: A: $2,240 - Incorrect because it does not account for the entire perimeter. B: $2,800 - Incorrect, as it underestimates the total cost. D: $4,480 - Incorrect, as it overestimates the total cost.

Correct Answer: C

Rationale: To determine the number of prizes for fifth-grade students, we need to allocate the prizes proportionally based on the number of students in each grade. 1. Calculate the total number of students in the school: 35 (Grade 1) + 38 (Grade 2) + 38 (Grade 3) + 33 (Grade 4) + 36 (Grade 5) = 180 students. 2. Calculate the proportion of students in fifth grade: 36 (Grade 5 students) / 180 (total students) = 0.2 or 20%. 3. Apply this proportion to the total number of prizes (20 prizes): 20 (total prizes) * 0.2 = 4 prizes for fifth-grade students. Therefore, the correct answer is B: 4 prizes for fifth-grade students. Other choices are incorrect because they do not accurately reflect the proportional allocation based on the number of students in each grade.

Correct Answer: B

Rationale: The correct answer is B (100 students passed the exam). Since all students who took the exam passed, if the class has 200 students, then all 200 students must have taken the exam, and all of them passed. Therefore, the total number of students who passed the exam is equal to the total number of students who took the exam, which is 200. So, the correct answer is 200 students passed the exam. Choices A, C, and D are incorrect because they do not reflect the fact that all students who took the exam passed.
