Answer:
1. 10% of the bill is $138. The final bill once 10% is taken off is $1242.
2. 20% of the total is $34.10. The final total once the 20% is taken off is $136.4
Step-by-step explanation:
1. A crash repair bill comes to $1380.00. How much is 10% of the bill? What is the final bill once 10% is taken off?
To find how much is 10% of the bill, we multiply the bill by 0.1
0.1*1380 = 138
10% of the bill is $138.
To find the final bill, we subtract the initial bill by 10%.
1380 - 138 = 1242
The final bill once 10% is taken off is $1242.
2. A person buys a new fan belt, a new alternator, and a new water pump for their car. The total comes to $170.50. What is 20% of the total? How much is the final total once the 20% is taken off?
Same logic as above.
0.2*170.50 = 34.1
20% of the total is $34.10.
170.50 - 34.1 = 136.4
The final total once the 20% is taken off is $136.4
 
        
             
        
        
        
So (positive integer)-x-y can be negative 
so to get a negative number as your result/answer, x+y must be greater than (positve integer) so  for example
lets say (positive integer)=8
x+y must be greater than 8 to make the equation negative so 
example
x=5
y=4
x+y=9
8-9=-1
        
             
        
        
        
Answer:
n is equal to 26
Step-by-step explanation:
Equation: n+ n + (n+2) +(n+2) = 108
so: 2n + 2(n+2) = 108
2n + 2n + 4 = 108
4n + 4 = 108
4n = 108 - 4
4n = 104
n = 104/4
n = 26
