Answer: 41
Step-by-step explanation:
If each line costs 2, then for the four-line ad, the cost is the initial price plus 4(2), meaning the initial cost is 25-8=17.

Not to be confused with the integral in the numerator:

but this integral is difficult to compute, hence the inequalities. We have




Answer:
176 sweets
Step-by-step explanation:
