An investor purchased shares of stock at a certain price. If the price of each share increases by $4.25 and the total value is$212.50, how many shares were purchased?
 a. 100 b. 60 c. 425 d. 50

#### Solution:

Let a be the number of shares of stock, the investor purchased.

The price of each share is increased by $4.25. The total price of stock is increased by$212.50.

Number of shares × increase in price of each share = Increase in total price of the stock.

a × 4.25 = 212.50
[Substitute the values.]

a = 212.504.25=50
[Divide each side by 4.25 and simplify.]

So, the investor purchased 50 shares of stock.

2.
Which operation would you use to solve 3$y$ = - $\frac{2}{5}$?
 a. multiply by - 5 b. divide by 3 c. divide by 5 d. multiply by 3

#### Solution:

3y = - 2 / 5
[Original Equation.]

To isolate the variable y, divide each side by 3.

3.
Solve 3$y$ = 30.
 a. 30 b. 10 c. 10 d. 20

#### Solution:

3y = 30
[Original equation.]

3y3 = 30 / 3
[Divide each side by 3.]

y = 10
[Simplify.]

4.
Solve 2$a$ = - 12.
 a. - 6 b. - 5 c. - 8 d. - 7

#### Solution:

2a = - 12
[Original equation.]

2a2 = - 122
[Divide each side by 2.]

a = - 6
[Simplify.]

5.
Solve = - 5.
 a. 25 b. 31 c. 27 d. 29

#### Solution:

m- 5 = - 5
[Original equation.]

(- 5) × m- 5 = (- 5) × - 5
[Multiply each side by - 5.]

m = 25
[Simplify.]

6.
Solve the equation.
9$m$ = - 36
 a. - 4 b. - 5 c. - 6 d. - 3

#### Solution:

9m = - 36
[Original equation.]

9m9 = - 369
[Divide each side by 9.]

m = - 4
[Simplify.]

7.
Solve the equation = 8.
 a. - 45 b. - 43 c. - 40 d. - 41

#### Solution:

m- 5 = 8
[Original equation.]

(- 5) × m- 5 = (- 5) × 8
[Multiply each side by - 5.]

m = - 40
[Simplify.]

The value of the variable m in the equation is - 40.

8.
Solve - 3$m$ = 96.
 a. 32 b. - 3.2 c. 3.2 d. - 32

#### Solution:

- 3m = 96
[Original equation.]

- 3m- 3 = 96m- 3
[Divide each side by - 3.]

m = - 32
[Simplify.]

9.
Which of the following would you use to solve $\frac{x}{7}$ = - 14?
 a. divide by - 7 b. divide by - 14 c. multiply by 7 d. multiply by 14

#### Solution:

x7 = - 14
[Original Equation.]

To isolate the variable x multiply each side by 7.

10.
What is the number, if one seventh of the number is 49?
 a. 8 b. 7 c. 343 d. 344

#### Solution:

Let p be the number.

p × 17 = 49
[Write an equation.]

p7 × 7 = 49 × 7
[Multiply each side by 7.]

p = 343
[Simplify.]

The number is 343.
