Answer:
22
Step-by-step explanation:
First write an expression to represent the situation.
$1,300,000 ≤ $475,000 + $37,500a
This expression works because the least amount of money that can make to remain profitable is 1,300,000. They already have 475,000 of that and every a (number of ads sold) is $37,500
Using this equation, solve for a.
1300000 ≤ 475000 + 37500a
First, subtract 475000 from both sides.
825000 ≤ 37500a
Then divide both sides of the equation by 37500 to isolate a.
22 ≤ a
22 is less than or equal to a. So they must sell at least 22 ads to remain profitable.
