For this case, the first thing we are going to do is define the following variable:

x = number of ads.

We then have the following mathematical expression that models the problem:

(100) * (1-0.3) * (x) = 375

Where,

100: Charges for each advertisement.

(1-0.3) : 30% discount per ad

x: number of ads

375: Budget available.

Clearing x we have:

x = (375) / ((100) * (1-0.3))

x = 5.357142857

Nearest whole number:

x = 5

Answer:

You can buy:

x = 5 ads.
