### Example Question #1 : How To Multiply Integers

in physics where.

If the mass is increased by 3 three times the original and the acceleration is increased by 7 times the original, how many times greater is the new force than the original force?

**Possible Answers:**

**Correct answer:**

We simply multiply the new mass by the new acceleration to obtain a new force that is 21 times greater than the original.

### 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:**

The office can only afford 20 computers.

### 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:**

**Correct answer:**

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.

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

Therefore, identifying the variables are as follows.

Substituting these into the fraction results in a possible time

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

Therefore, identifying the variables are as follows.

Substituting these into the fraction results in a possible time

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