Question

Belinda will earn $46,000 her first year working as an interior designer with annual raises of 10%. What are her total earning at the end of 7 years?

Answer 1

For this case we have an equation of the form:
 y = A * (b) ^ t
 Where,
 A: initial gain
 b: growth rate
 t: time
 Substituting values we have:
 y = 46000 * (1.10) ^ t
 For the year 7 we have:
 y = 46000 * (1.10) ^ 7
 y = 89640.9866
 Answer:
 her total earning at the end of 7 years are:
 y = 89640.9866 $
