Answer:
$1.80
Step-by-step explanation:
Use formula 

where I is interest, P is total principal, i is rate of interest per year (as decimal) and t is total time in years.
In your case, 
I=$36.45, t=312, i=0.065, then
 
 
        
                    
             
        
        
        
If I’m correct negative one half
        
             
        
        
            
            
                A single die is rolled twice. the set of 36 equally likely outcomes is {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 1),  
                Maksim231197 [3]             
         
        
<span>We need to find the rolls whose sum is greater than 10. By looking at the outcomes, we see that (5,6), (6,5), and (6,6) all have a sum greater than 10. Therefore, there are 3 chances to get a sum greater than 10. Since there are 36 chances overall, the probability of rolling greater than 10 are 3/36 = 1/12.</span>
        
             
        
        
        
<span>I will assume the more likely selection of $10 per sandal as opposed to $0.05 per sandal.
So with the formulas
c = 1000 + 5x
r = 75x - 0.4x^2
Sandals	Cost	Revenue	Profit or Loss
0	$1,000.00	$0.00	-$1,000.00
1	$1,005.00	$74.60	-$930.40
2	$1,010.00	$148.40	-$861.60
3	$1,015.00	$221.40	-$793.60
4	$1,020.00	$293.60	-$726.40
5	$1,025.00	$365.00	-$660.00
6	$1,030.00	$435.60	-$594.40
7	$1,035.00	$505.40	-$529.60
8	$1,040.00	$574.40	-$465.60
9	$1,045.00	$642.60	-$402.40
10	$1,050.00	$710.00	-$340.00
11	$1,055.00	$776.60	-$278.40
12	$1,060.00	$842.40	-$217.60
13	$1,065.00	$907.40	-$157.60
14	$1,070.00	$971.60	-$98.40
15	$1,075.00	$1,035.00	-$40.00
16	$1,080.00	$1,097.60	$17.60
17	$1,085.00	$1,159.40	$74.40
18	$1,090.00	$1,220.40	$130.40
19	$1,095.00	$1,280.60	$185.60
20	$1,100.00	$1,340.00	$240.00
As you can see 16 sandals and up is profitable.
At what production levels will the company lose money?
a. between 0 and 10 or between 150 and 190 pairs, inclusive
150 and 190
c. between 10 and 20 or between 50 and 100, inclusive
If you add up the profit between 10 and 20 you will get $-484 so 50 and 100
b. between 0 and 15 or between 160 and 200 pairs, inclusive
160 and 200
d. between 15 and 35 or between 75 and 125, inclusive
Neither 15 and 35 or 75 and 125 will lose money.</span>
        
             
        
        
        
Answer:
- 3
Step-by-step explanation:
let n be the number , then
3n + 4 = n - 2 ( subtract n from both sides )
2n + 4 = - 2 ( subtract 4 from both sides )
2n = - 6 ( divide both sides by 2 )
n = - 3
The number is - 3
