Answer:
Step-by-step explanation:
According to the problem, the initial condition is $200. If he owed $100 after 4 weeks, that means he paid $25 per week, so that would be the constant ratio. Therefore, the expression would be:
Where 
represents the amount owed, and 
represents weeks.
So, in the 4 week, that is, 
he owed:
As you can observe, the relation we found first perfectly to the problem. So, the final expression that model this problem is
The correct answer is c (2x+10)
I think her error was that she multiplied he numbers wrong
7) x= men
x+6= women
x + (x+6)= 30
2x + 6= 30
2x= 24
x= 12
x+6= 18
8) x= first integer
x+1= second integer
x+2= third integer
x + (x+1) + (x+2)= 153
3x + 3= 153
3x= 150
x= 50
Second integer
= x+1
= x+50
= 51
9) x= first integer
x+2= second integer
x+4= third integer
x + (x+2) + (x+4)= 54
3x + 6= 54
3x= 48
x= 16
x + (x+2)= 34
16 + 16 + 2= 34
34=34
10) rate= 356 km/hr
distance= 1424 km
Distance= rate * time
D= rt
1424= 356 * t
divide both sides by 356
4 hrs= t
