Question 1186213
Architect Cristobal made $35,000 during the first year of his job. Each year, he received a 20% raise. What were his total earnings during the first ten years on the job? 

Sum of numbers in a G P= a1(r^n -1)/r-1 

a1=35000

r=1.2
n=10
substitute with values in the   formula

A=  35000*(1.2^10 -1)/(1.2-1)

=181710.774/0.2

= 908553.88


 total earnings during the first ten years=$ 908553.88
