Karen will be payed $60 in interest in the first four years. 

We can solve this problem by using the simple interest formula (Interest = Principal * Rate * Time)

Interest = 300 * 5/100 * 4

Interest = 60, meaning that Karen will be payed $60 in interest in the first four years.

-7x + 8y = 19<br> 7x – 9y=-17
Gemiola [76]

Answer:

Solution set = (-5, -2)

Step-by-step explanation:

Given equations;

-7x + 8y = 19  ------------- eq1

7x – 9y=-17  --------------- eq2

Adding both equations:

-y = 2

OR

y = 2

Put value of y in eq2:

7x - 9(-2) = -17

7x + 18 = -17

7x = -17 -18

7x = -35

x = -5

Solution set = (-5, -2)

i hope it will help you!

On a certain hot summer day, 738 people used the public swimming pool.The daily prices are 1.50 for children and 2.00 for adults
Artemon [7]

Answer:

A = 340 adult.

C = 398 children.

Step-by-step explanation:

Let the number of children be C

Let the number of adults be A

Translating the word problem into an algebraic equation, we have;

A + C = 738  .......equation 1

1.5C + 2C = 1306  .......equation 2

A = 738 - C .......equation 3

Substituting eqn 3 into eqn 2, we have;

1.5(738 - C) + 2C = 1306

1107 - 1.5C + 2C = 1306

1306 - 1107 = 2C - 1.5C

199 = 0.5C

C = 199/0.5

<em>C = 398 children. </em>

Now, to find the value of A.

From equation 3;

A = 738 - C

A = 738 - 398

<em>A = 340 adult. </em>
