TEAS Test Practice Math Questions
Question 1 of 5
In the winter of 2006, 6 inches of snow fell in Chicago, IL. The following winter, 3 inches of snowfall fell in Chicago. What was the percent decrease in snowfall in Chicago between those two winters?
Correct Answer: C
Rationale:
To calculate the percent decrease in snowfall between the two winters, use the formula: Percent Decrease = ((Initial Value - Final Value) / Initial Value) * 100. In this case, the initial value is 6 inches and the final value is 3 inches. Plug these values into the formula: ((6 - 3) / 6) * 100 = (3 / 6) * 100 = 0.5 * 100 = 50%.
Therefore, the correct answer is 50%, which is not listed among the choices provided. Among the given choices, the closest percentage is 41.00%, which corresponds to choice C.
Question 2 of 5
The cost, in dollars, of shipping x computers to California for sale is 3000 + 100x. The amount received when selling these computers is 400x dollars. What is the least number of computers that must be shipped and sold so that the amount received is at least equal to the shipping cost?
Correct Answer: B
Rationale:
To find the least number of computers that must be shipped and sold so that the amount received is at least equal to the shipping cost, we set up the inequality 400x >= 3000 + 100x. Simplifying this inequality gives 300x >= 3000, and dividing by 300 results in x >= 10.
Therefore, at least 15 computers must be shipped and sold to cover the shipping cost, making choice B the correct answer.
Choices A, C, and D are incorrect as they represent numbers less than 15, which would not cover the shipping cost.
Question 3 of 5
A woman wants to stack two small bookcases beneath a window that is 26 inches from the floor. The larger bookcase is 14 inches tall. The other bookcase is 8 inches tall. How tall will the two bookcases be when they are stacked together?
Correct Answer: B
Rationale: When the woman stacks the two bookcases together, the total height will be the sum of the heights of the two bookcases.
Therefore, 14 inches (larger bookcase) + 8 inches (smaller bookcase) = 22 inches. So, the stacked bookcases will be 22 inches tall.
Choice A is incorrect because it does not account for the total height of both bookcases.
Choice C and D are incorrect as they are higher than the combined height of the two bookcases.
Question 4 of 5
Solve the following equation: 3(2y+50)−4y=500
Correct Answer: B
Rationale:
To solve the equation 3(2y+50)−4y=500, first distribute to get 6y+150−4y=500. Combining like terms results in 2y + 150 = 500. By subtracting 150 from both sides, we get 2y = 350. Dividing by 2 gives y = 175.
Therefore, the correct answer is B.
Choices A, C, and D are incorrect because they do not correctly follow the steps of distributing, combining like terms, and isolating the variable to solve for y.
Question 5 of 5
Approximately by what percentage are there more female staff members in City Y compared to City X?
Correct Answer: D
Rationale:
To find the percentage difference in female staff members between City Y and City X, you subtract the percentage of female staff members in City X from the percentage in City Y. So, 60% (City Y) - 40% (City X) = 20%. This means there are 20% more female staff members in City Y compared to City X.
Choices A, B, and C are incorrect percentages and do not accurately represent the 20% difference between the two cities.
