Answer:
8 ads
Step-by-step explanation:
To start off, we know we have a budget of $500 which means we cannot go above that amount. Ads cost $75 each but in our case they are now 20% cheaper. Lets figure out the new price of the ads. Remember to change 20% into its decimal form (20% -> 0.2)
75 x 0.2 = 15
Now we subtract 15 from 75 to get our new ad price.
75 - 15 = 60
Now to figure out how many ads we can get with a budget of $500, we simply divide 500 by 60. Don't forget to round the answer to the nearest whole number since we cannot go over our budget.
500 / 60 = 8 ads
