TEAS Practice Test Math
1. A couple dining at a restaurant receives a bill for $58.60. They wish to leave a 16% gratuity. Which of the following is the estimated gratuity?
- A. $8.48
- B. $6.40
- C. $9.38
- D. $7.00
Correct answer: C
Rationale: To calculate a 16% gratuity on a bill of $58.60, you multiply $58.60 by 0.16, which equals $9.376. Rounding this to the nearest cent gives $9.38. Therefore, the estimated gratuity is $9.38. Choice A is incorrect as it does not accurately reflect the calculated amount. Choice B is also incorrect as it does not match the correct calculation. Choice D is incorrect as it is not the nearest estimated value to the calculated amount.
2. Approximately what percentage more staff members at Hospital Y are female than at Hospital X?
- A. 5
- B. 10
- C. 15
- D. 20
Correct answer: B
Rationale: To find the percentage more staff members at Hospital Y are female than at Hospital X, we first calculate the percentage of female staff members at each hospital. For Hospital Y: (90 / 183) x 100 โ 49.2%. For Hospital X: (97 / 250) x 100 โ 38.8%. The difference between these percentages is approximately 10%, making choice B the correct answer. Choice A, 5%, is too low as the difference is greater. Choice C, 15%, and choice D, 20%, are both too high as the actual difference is closer to 10%.
3. Which of the following is the correct decimal placement for the product of 1.6 * 0.93?
- A. 14.88
- B. 0.1488
- C. 1.488
- D. 0.001488
Correct answer: C
Rationale: To find the product of 1.6 * 0.93, you multiply these two numbers to get 1.488. Therefore, the correct decimal placement for the product is 1.488. Choice A, 14.88, is incorrect as it incorrectly places the decimal two spots to the right. Choice B, 0.1488, is incorrect as it incorrectly places the decimal one spot to the right. Choice D, 0.001488, is incorrect as it incorrectly places the decimal three spots to the right.
4. Simplify the expression: 2x + 3x - 5.
- A. 5x - 5
- B. 5x
- C. x - 5
- D. 2x - 5
Correct answer: A
Rationale: To simplify the expression 2๐ฅ + 3๐ฅ - 5, follow these steps: Identify and combine like terms. The terms 2๐ฅ and 3๐ฅ are both 'like terms' because they both contain the variable ๐ฅ. Add the coefficients of the like terms: 2๐ฅ + 3๐ฅ = 5๐ฅ. Simplify the expression. After combining the like terms, the expression becomes 5๐ฅ - 5, which includes the simplified term 5๐ฅ and the constant -5. Thus, the fully simplified expression is 5๐ฅ - 5, making Option A the correct answer. This method ensures all terms are correctly simplified by combining similar elements and retaining constants.
5. Which of the following describes a graph that represents a proportional relationship?
- A. The graph has a slope of 2,500 and a y-intercept of 250
- B. The graph has a slope of 1,500 and a y-intercept of -150
- C. The graph has a slope of 2,000 and a y-intercept of 0
- D. The graph has a slope of -1,800 and a y-intercept of -100
Correct answer: C
Rationale: A graph that has a y-intercept of 0 indicates a proportional relationship because the starting value is 0, and no amount is added to or subtracted from the term containing the slope. In this case, choice C is correct as it has a y-intercept of 0, which aligns with the characteristics of a proportional relationship. Choices A, B, and D have non-zero y-intercepts, indicating a starting value other than 0, which does not represent a proportional relationship.
