Answer:
10 of each Ad should be used
Step-by-step explanation:
Assuming that the numbers provided are correct, then the mayoral candidate should max out the number of ads on each platform since only 10 ads of each type can be used, and doing so does not max out the campaign budget. This would allow you to max out the number of individuals you can reach. The math would be the following...
Radio:
10 * $200 = $2000 total spent
10 * 3000 = 30,000 people reached
TV:
10 * $500 = $5000 total spent
10 * 7000 = 70,000 people reached
Total:
$2000 + $5000 = $7000 total spent
30,000 * 70,000 = 70,000 people reached
