larisa86 [58]

Answer:

It would cost $600 for an advertisement of $\frac{3}{4}$ of a page.

Step-by-step explanation:

Given:

To place an ad in the Harrisonburg newspaper it cost $100 for each 1/8 of a page used.

Now, to find the cost of an advertisement 3/4 of a page.

So, to get the cost we use unitary method:

If, $\frac{1}{8}$ of a page used cost = $100.

Then, 1 page used cost = $100\div \frac{1}{8}$ = $\$800.$

Thus, $\frac{3}{4}$ of a page used cost = $800\times \frac{3}{4} =\frac{2400}{4}=\$600.$

Therefore, it would cost $600 for an advertisement of $\frac{3}{4}$ of a page.
