2:3:5
2x+3x+5x=180
10x=180
x=18
2x=36
3x=54
5x=90
        
                    
             
        
        
        
Intersection (repeated element in the set)
A={-9,0,5} 
B={0,2,5,8}
C={-9,2,5}
Ans: C, {5}

Find how much interest is earned for one year: $3000 x .015 = $45
Use that answer to find how much interest is earned for 15 years: $45 x 15 years = $675
Add original investment to interest for balance: $3000 + $675 = $3675
