Ответ:
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
You can buy:
x = 5 ads.
