X - invested for the money at 11%
70 000 - x - deposited at 12%
0.11x + 0.12(70000-x)=7900
0.11x + 8400 - 0.12x = 7900
8400- 7900 = 0.01x
500 = 0.01x
x=50 000 invested at 11%
rest (20K) invested at 12%
        
             
        
        
        
Answer:
4 weeks and 2 days
Step-by-step explanation:
There are 7 days in one week.
To convert 30 days into weeks and days, divide 30 by 7.
The biggest number you can divide it by is 4 [without going over 30]
7 x 4 = 28. 
30 - 28 = 2.
So 30 days = 4 weeks and 2 days.
I hope this helps! :)
 
        
                    
             
        
        
        
Answer:Paul should sell 3 paintings per hour to recover his cost.

5 hours = 14 paintings
1 hour =  
Rounding off to nearest whole number;
2.8 paintings = 3 paintings
