Answer:
20 adults and 10 children
Step-by-step explanation:
We need to find the total amount of adults and children for 30 total people (adults + children) and only 100$ for them. 30 adults is 120$. We need to take off double the amount of money that would bring it to 100$ because the cost for each child is half of an adult. That way, we have 80$ of adults, and when we fill in the rest with children, we get to 100$ total and 30 total people.
Answer:
f(2) =8
Step-by-step explanation:
f(2) Is when n=2
f(2) = -5 *f(2-1) -7
f(2) = -5 *f(1) -7
We know that f(1) = -3
f(2) = -5 *-3 -7
= 15 -7
= 8
