Practice Math TEAS TEST

Correct Answer: D

Rationale: To find the teacher's total earnings after deductions for 4 weeks, we first calculate the total deductions per week: $72 + $35 + $65 = $172. Then, subtract this total from the teacher's weekly earnings: $730 - $172 = $558. Multiply this by 4 weeks: $558 * 4 = $2,232. Therefore, the correct answer is D. Option A is too low, as it does not account for the deductions. Option B is too high, as it overestimates the earnings. Option C is also incorrect, as it does not consider the deductions accurately.

Correct Answer: A

Rationale: To find the sum of three times a number and eight times a different number, we need to add 3 times the first number (3x) to 8 times the second number (8y). Therefore, the correct expression is 3x + 8y (Choice A). This choice correctly represents the operation of adding the terms. Choices B, C, and D either incorrectly combine the coefficients of x and y or use subtraction instead of addition, making them incorrect for this question.

Correct Answer: C

Rationale: The correct answer is C: 5 in the second decimal place. In the number 0.08573, the digit 5 is in the second decimal place after the decimal point. The first decimal place is occupied by 0, the second by 8, the third by 5, the fourth by 7, and the fifth by 3. Therefore, the correct positioning of decimal places in this number is as follows: 0.0 8 5 7 3. Choices A, B, and D are incorrect because they do not accurately represent the positioning of decimal places in the given number.

Correct Answer: B

Rationale: To find the median, first, sort the data set in ascending order: -3, -2, 0, 5, 10. The middle value is the median, which is 0 in this case. This is the correct answer (B). The other choices are incorrect because: A: 10 is the highest value, not the middle value. C: 5 is not the middle value when the data set is arranged in ascending order. D: 2 is not present in the data set, making it an invalid choice.

Correct Answer: D

Rationale: To calculate a 10% tip on a $28.40 bill, you multiply $28.40 by 0.10, which equals $2.84. Rounding up to the nearest dollar gives an estimated gratuity of $3.00. Choice D is correct because it accurately represents a 10% tip on the bill. Choices A, B, and C are incorrect as they do not reflect the correct calculation for a 10% tip on the given bill amount.
