Answer:

$255

Step-by-step explanation:

To find amount that is subtracted off of the original price, you would need to multiply 300 by 15% as a decimal

The decimal form of 15% is 0.15, meaning that you would have to multiply 300 and 0.15

Once you do this, you will get 45

To find the sale price, you need to subtract the amount that is discounted, 45, from 300

Once you do this, you will get 255

This means that the sale price of the item is $255

e. Translate the word problem below into an equation; then solve. It only takes Vera 2 hours to sew 1 dress, but it takes Ivy 4

Daniel [21]

Using the together rate, it is found that it would take them 16 hours to sew 12 dresses.

<h3>What is the together rate?</h3>

The together rate is the <u>sum of each separate rate</u>.

In this problem, we have that:

Vera's rate is of 1/2.

Ivy's rate is of 1/4.

Hence, the together rate is the time it would take them to produce one dress working together, and is given by:

$\frac{1}{x} = \frac{1}{2} + \frac{1}{4}$

$\frac{1}{x} = \frac{2 + 1}{4}$

$3x = 4$

$x = \frac{4}{3}$

Then one dress takes $\frac{4}{3}$ of an hour, and the time for twelve dresses is:

$t = 12 \times \frac{4}{3} = 4(4) = 16$

It would take them 16 hours to sew 12 dresses.
