Whats the unit rate for $2.50 for 5 ounces
kumpel [21]

For this case what we should do is find the cost per ounce.

For this, we can use the following rule of three:

5 ounces ----------------------> 2.50 $

1 oz ------------------------> x

From here, we clear the value of x.

We have then:

x = (\frac{1}{5}) * (2.50)\\x = 0.5

Answer:

The unit cost per ounce is given by:

x = 0.5 $ / ounce

A sweater originally priced at $79 is marked down 20%. What will the sales piece be?
ivann1987 [24]

Answer:

$63.20

Step-by-step explanation:

first we have to find how much the sweater is marked down in money. we do this by converting the percentage to decimal form and multiply by the original price.

79•0.2= 15.8

so the sweater is marked down $15.80. now we subtract that markdown from the original price to find the new price

$79-$15.8= $63.20

hope this helps chu <3
