Question 1

Some states use sales tax to raise revenue. How much money will be collected on the sale of a $16,000 car if the sales tax rate is 5%?

Accepted Answer

The sales tax on a $16,000 car at a rate of 5% is calculated as $16,000 * 0.05 = $800.

Question 2

After the first day of registration, 100 children had been enrolled in a new day care center. That represented 50% of the available slots. What was the maximum number of children the center could enroll?

Accepted Answer

If 100 children represent 50% of the available slots, then there are a total of 200 available slots. This can be found by using the equation: 
100 = 0.5x (where x is the total number of available slots) 
Solving for x: 
200 = x 
Therefore, the maximum number of children the center could enroll is 200.

Question 4

In 1988 10% of adult Americans said the car was the greatest invention of all time. Assuming the same facts apply today and assuming that there are 200 million adult Americans, how many adult Americans say the car is the greatest invention of all time?

Accepted Answer

To find the number of adult Americans who say the car is the greatest invention of all time, calculate 10% of 200 million: $200,000,000 \times 0.10 = 20,000,000$.

Question 6

On the written part of his driving test, a man answered 25 out of 40 questions correctly. If 65% correct is passing, did he pass the test?

Accepted Answer

To determine if he passed the test, we need to find what percentage of questions he answered correctly. We can set up a proportion:
\begin{align*}
\frac{	ext{number of correct answers}}{	ext{total number of questions}} &= \frac{x}{100\%}\
\frac{25}{40} &= \frac{x}{100\%}\
40x &= 2500\
x &= 62.5
\end{align*}
Therefore, he only answered 62.5% of the questions correctly, which is less than the passing grade of 65%. Therefore, he did not pass the test. The answer is choice B, no.
