Possible Answers:

$0$

$7$

$3$

Example Question #1 : How To Multiply Integers

An office wants to buy 22 computers at $900 each. The budget is $20,000 and the tax on computers is 9%. How many computers can the office afford?

Possible Answers:

Correct answer:

Explanation:

The office can only afford 20 computers.

1.09 * 900 = $981 is the actual price of each computer, with tax.

Divide:

20,000/981 = 20.39

Since the office cannot purchase a partial computer, we round down to 20 computers.

Correct answer:

Explanation:

First, divide by to determine how many walls the paint crew can paint in hour.

$\frac{45}{15}=\frac{15\cdot 3}{15}=3$

divided by is equal to .

Then, multiply this number by hours.

$8\cdot 3=24$

Example Question #1 : New Sat Math Calculator

Convert three yards to inches.

Possible Answers:

$110\text{ inches}$

$92\text{ inches}$

$88\text{ inches}$

$108\text{ inches}$

$64\text{ inches}$

Correct answer:

$108\text{ inches}$

Explanation:

To solve this problem, we need to know the conversions between yards to feet, and feet to inches. Write their correct conversions.

$1 \textup{ yard}= 3\textup{ feet}$

$1\textup{ foot}= 12 \textup{ inches}$

Convert three yards to feet.

$3 \textup{ yards}\left(\frac{3 \textup{ feet}}{1 \textup{ yard}}\right)= 9 \textup{ feet}$

Convert nine feet to inches.

$9 \textup{ feet}\left(\frac{12 \textup{ inches}}{1 \textup{ foot}}\right)= 108\textup{ inches}$

Example Question #867 : Arithmetic

Calculate in the following series:

A,10, 16 , 80, 86, 430, 436, 2180,...

Possible Answers:

Correct answer:

Explanation:

Each element is obtained from the previous one by alternating the following operations: multiplying by 5 and adding 6.

$\begin{matrix} 10+6 = 16\\ 16 \times 5 = 80 \\ 80+6 = 86 \\\; \; 86 \times 5 = 430 \\ \; \; 430+6 = 436\\ \; \; 436 \times 5 = 2180 \end{matrix}$

If we let be the first element, then

$A \times 5 = 10$

Solve for :

$A \times 5 \div 5 = 10 \div 5$

A = 2

Example Question #2 : How To Multiply Integers

Janet can pick between 10 and 20 tomatoes in an hour. What is a possible amount of time for Janet to pick 120 tomatoes?

Possible Answers:

$5\text{ hours}$

$16\text{ hours}$

$4\text{ hours}$

$6\text{ hours}$

$20\text{ hours}$

Correct answer:

$6\text{ hours}$

Explanation:

Since Janet can pick between 10 and 20 tomatoes in an hour, there is a range for which she can pick 120 tomatoes. Therefore, to find the possible amount of time it will take Janet to pick 120 tomatoes set up two fractions.

$\text{Time}_1=\frac{\text{Total Tomatoes Picked}}{\text{Rate}_1}$

The first fraction will use the rate of 10 tomatoes an hour.

Therefore, identifying the variables are as follows.

$\\\text{Total Tomatoes}=120 \\\text{Rate}_1=10$

Substituting these into the fraction results in a possible time

$\text{Time}_1=\frac{120}{10}=\frac{12\times 10}{10}=12\text{ hours}$

The second fraction will use the rate of 20 tomatoes an hour.

$\text{Time}_2=\frac{\text{Total Tomatoes Picked}}{\text{Rate}_2}$

Therefore, identifying the variables are as follows.

$\\\text{Total Tomatoes}=120 \\\text{Rate}_2=20$

Substituting these into the fraction results in a possible time

$\text{Time}_1=\frac{120}{20}=\frac{6\times 20}{20}=6\text{ hours}$

Of the answer selections 6 hours would be the correct answer.
