The theater charges $5.5 per ticket per person of any age group.
Your expression would not have $5.5c or $5.5a as they have a price for only one variable.
Your expression would be 5.5(a+c).
Your first option is the correct one.
The population in 2016 is likely to be 206.20 million.
Given:
Let the population in 1994 be P₀ and g be the exponential growth.
Let the population Pn in nth will be denoted by Pn = P₀ * (1+g)n.
The population in 1994 was 195 million and after 8 years it became 199 million in 2002.
So,
199 = 195 * (1+g)₈ = 199195
Using log,
=8 * log(1+g) = log199 - log195 = 0.0088185
=log(1+g) = 0.0011022
=1 + g = 1.002541
g = 0.00254
Therefore the growth rate is 0.2541%
The population in 2016 is computed by:
= 195 * (1+g)₂₂ or 195 * 1.002541₂₂
= 195 * 1.0574279
= 206.20 million
add all the numbers without a minus.
