Question 1 of 5
Which of the following translates the phrase '5 less than 2 times a number' into a mathematical expression?
Correct Answer: C
Rationale: To translate the phrase '5 less than 2 times a number' into a mathematical expression, you first express '2 times a number' as 2x. Then, '5 less than' indicates subtracting 5 from the result, leading to 2x - 5. Therefore, choice C, 2x - 5, correctly represents the given phrase in a mathematical expression.

Question 2 of 5
If a box of 35 syringes costs $560.00, what is the cost for two syringes?
Correct Answer: D
Rationale: To determine the cost for two syringes, you first need to calculate the cost per syringe by dividing the total cost of the box by the total number of syringes in the box: $560.00 � 35 syringes = $16.00 per syringe. Therefore, each syringe costs $16.00. To find the cost of two syringes, you multiply the cost per syringe by 2: $16.00 x 2 = $32.00. Hence, the correct answer is option D, which is $32.00 for two syringes.
Question 3 of 5
A couple dining at a restaurant receives a bill for $38.40. They wish to leave a 15% gratuity. What is the estimated gratuity amount?
Correct Answer: A
Rationale: To calculate the 15% gratuity on a $38.40 bill, you multiply the bill amount by 0.15 (15%): $38.40 x 0.15 = $5.76. Since gratuity amounts are typically rounded up, the estimated gratuity would be $6.00, making choice A the correct answer. In this case, rounding up to the nearest whole dollar is common practice in gratuity calculations to simplify tipping and ensure a fair amount for the service provided.
Question 4 of 5
In the graph above, which represents the amount of rainfall in a particular state by month, what is the total rainfall for the first 3 months of the year?
Correct Answer: A
Rationale: To calculate the total rainfall for the first 3 months of the year, you need to add the rainfall amounts for January (1 inch), February (1/2 inch), and March (2 inches) together. This sum gives a total of 3 1/2 inches, making choice A the correct answer.
Question 5 of 5
A couple dining at a restaurant receives a bill for $38.40. They wish to leave a 15% gratuity. What is the estimated gratuity amount?
Correct Answer: B
Rationale: To calculate a 15% gratuity on a $38.40 bill, you multiply $38.40 by 0.15 (15%). This calculation results in $5.76, which is the estimated gratuity amount. Therefore, the correct answer is $5.76 (Choice B). Leaving a 15% gratuity is a common practice to show appreciation for the service provided by the restaurant staff.
