Answer:

580

Step-by-step explanation:

Let's translate this word for word.

87 is 15% of what number

87 = 15% times x

87=.15 times x

$87=.15 \cdot x$

Divide both sides by .15

$\frac{87}{.15}=\frac{.15x}{.15}$

Cancel out the common factor of .15 on the right; that is .15/.15=1.

$580=x$

580 is the number

Answer:

580

Step-by-step explanation:

Alright. Translate that into math, and you get:

87=15/100x

multiply both sides by x

8700/15=x

x=8700/15

x=580

Check:

580*15/100

58*15/10

870/10

BINGO!

This process is very simple. All you are doing is creating a table of values somewhere to help you graph this function. As you can see, the coordinates of $\displaystyle [-6, -2], [1, -1], [2, 0], [3, 1],$ and $[10, 2]$ are all touched on this graph, letting you know that this information is accurate.
