Mr. Stanton bought 2.6 yards of fabric for $8.94. About how much was the cost per yard?
lapo4ka [179]

In order to find CPU (Cost per unit) we must take the cost, and divide it by the number of units.

So,

\$8.94\div2.6=\$3.4384

Since we are talking about money, it is implied to round to the nearest cent, so the final answer is

$3.44

Evaluate the replacement set for the following equation 2n - 3 &lt; 9. replacement set : n = {2, 5, 0}
ad-work [718]

n = {2, 5, 0} holds true for 2n - 3 < 9

<em><u>Solution:</u></em>

Replacement set is the set of values that may be substituted for the variable.

Plug in each value from the replacement set and evaluate both sides of the inequality

If the inequality is true for a certain value, that value belongs in the solution set.

<em><u>Given equation is:</u></em>

2n - 3 < 9

<em><u>Substitute n = 2</u></em>

2(2) - 3 < 9

4 - 3 < 9

1 < 9

1 is less than 9 is true

Thus n = 2 is a solution to equation

<em><u>Substitute n = 5</u></em>

2(5) - 3 < 9

10 - 3 < 9

7 < 9

7 is less than 9 is true

Thus n = 5 is a solution to equation

<em><u>Substitute n = 0</u></em>

2(0) - 3 < 9

0 - 3 < 9

-3 < 9

-3 is less than 9 is true

Thus n = -3 is a solution to equation
