Answer:
B
Step-by-step explanation:
The given equations satisfy the given conditions. There are 2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
 
        
             
        
        
        
If interest is 5 percent then you add 5 for every 100 so
6x5=30 
then you add 30 to 600 so your answer is 630
        
             
        
        
        
ANSWER: 7.53
