Answer: It will reduce taxes by $2.8 million.
Step-by-step explanation:
Expenses are tax deductible which means that the advertising expense will reduce tax by 35% of it's value.
= 8,000,000 * 35%
= $2,800,000
Expenses of $8,000,000 will reduce pre-tax profit by the same amount which would lead to taxes being $2,800,000 lower.
