It will take 36.6 or 37 months.
We will set up an equation to represent this. Let m be the number of months. The amount of money she has paid can be represented by 3000+430m. The amount of money her car is worth can be represented by 26868-223m. Set these equal:
3000+430m=26868-223m
Add 223m to both sides:
3000+430m+223m = 26868-223m+223m
3000+653m=26868
Subtract 3000 from both sides:
3000+653m-3000 = 26868-3000
653m=23868
Divide both sides by 653:
653m/653 = 23868/653
m = 36.6
Answer:
$26.31
Step-by-step explanation:
Since 3 is half of 6, 3 pairs of shoes would cost half the price.
So...
52.62/2=$26.31
The first one is X, then the second one would be X+1 ( adding one, makes it consecutive).
Now you have X + X+1 = 667
Simplify:
2x +1 = 667
Subtract 1 from each side:
2x = 666
Divide both sides by 2:
x = 666 /2
x = 333
The first marker is 333
The second marker = 333 +1 = 334
