TEAS Exam Math Practice Questions
Question 1 of 5
A restaurant employs servers, hosts, and managers in a ratio of 9:2:1. If there are 36 total employees, what is the number of hosts at the restaurant?
Correct Answer: C
Rationale:
To find the number of hosts in the restaurant, first, express the ratio algebraically as 9x + 2x + 1x = 36, where x represents the common factor. Combine like terms to get 12x = 36. Solve for x by dividing both sides by 12 to get x = 3.
To find the number of hosts, multiply the coefficient of hosts (2) by x, which equals 6.
Therefore, there are 6 hosts at the restaurant.
Choice A, 3, is incorrect as it represents the number of servers.
Choices B and D are incorrect as they do not correspond to the number of hosts based on the given ratio.
Question 2 of 5
A woman's dinner bill comes to $48.30. If she adds a 20% tip, which of the following will be her total bill?
Correct Answer: D
Rationale:
To calculate the total bill after adding a 20% tip, you need to find 120% of the original bill. This is because adding a 20% tip means paying 120% of the bill. So, $48.30 120/100 = $57.96.
Therefore, the correct answer is $57.96.
Choice A ($9.66) is incorrect as it represents only the 20% tip amount.
Choice B ($38.64) is incorrect as it is the original bill amount without the tip.
Choice C ($48.30) is incorrect as it is the original bill amount and does not include the additional 20% tip.
Question 3 of 5
Which of the following lists is in order from least to greatest? 2−1 , −(4/3), (−1)3 , (2/5)
Correct Answer: D
Rationale:
To determine the correct order from least to greatest, start by simplifying the expressions. 2^(-1) = 1/2 and (-1)^3 = -1. Now, comparing the values, (-4/3) is the most negative, followed by -1, then (2/5), and finally 1/2.
Therefore, the correct order is (-4/3), (-1)^3, (2/5), 2^(-1), making choice D the correct answer.
Choices A, B, and C are incorrect because they do not follow the correct order from least to greatest as determined by comparing the values of the expressions after simplification.
Question 4 of 5
What is the area of a triangle with a base of 10 cm and a height of 7 cm?
Correct Answer: B
Rationale:
To find the area of a triangle, you use the formula A = 1/2 base height. Substituting the given values: A = 1/2 10 cm 7 cm = 35 cm².
Therefore, the correct answer is B.
Choice A (70 cm²) is incorrect as it seems to be the product of the base and height rather than the area formula.
Choice C (140 cm²) is incorrect as it appears to be twice the correct answer, possibly a result of a miscalculation.
Choice D (100 cm²) is incorrect as it does not reflect the correct calculation based on the given base and height values.
Question 5 of 5
A dry cleaner charges $3 per shirt, $6 per pair of pants, and an extra $5 per item for mending. Annie drops off 5 shirts and 4 pairs of pants, 2 of which need mending. Assuming the cleaner charges an 8% sales tax, what will be the amount of Annie's total bill?
Correct Answer: C
Rationale:
To determine the total cost before tax, calculate: 5 shirts $3/shirt + 4 pants $6/pair of pants + 2 items mended $5/item mended = $49. Now, multiply this amount by 1.08 to include the 8% sales tax: $49 1.08 = $52.92.
Therefore, Annie's total bill will be $52.92.
Choice A, $45.08, is incorrect as it does not include the correct calculation for the total bill.
Choice B, $49.00, is wrong because it is the total cost before tax and does not consider the added sales tax.
Choice D, $88.20, is incorrect as it does not accurately calculate the total bill including the sales tax.
