Question

Write the phrase as a unit rate. $13.50 for 3.6 lb Alb Please help FAST

Answer 1

Answer:

$3.75/lb

Step-by-step explanation:

First, let's set up a proportion. The top number represents the cost, while the bottom number represents how many pounds. In order to get a unit rate, we need to figure out how much it costs for 1 pound.

$\frac{13.5}{3.6} =\frac{x}{1}$

Now, cross multiply. To cross multiply, you would multiply 13.5 by 1 and 3.6 by x.

$13.5 * 1 =13.5\\3.6*x=3.6x$

Set these two equal to each other.

$13.5=3.6x$

Divide both sides by 3.6 to get x.

$\frac{13.5}{3.6} =\frac{3.6x}{3.6}\\x=3.75$

For unit rates, you have to write your answer as per unit. To do that, put a slash next to your answer, and then your unit.

$3.75 / lb (unit)
