Answer:
20 months
Step-by-step explanation:
Let the number of months be denoted by x.
Then, we shall form two equations to represent the total cost from each dealer. Thus,
2500 + 150x is the cost of the motorcycle from the first dealer.
3000 + 125x is the cost of the motorcycle from the second dealer.
If the costs from the dealers are equal, then
2500 + 150x =3000 +125x
150x- 125x = 3000-2500
25x = 500
x = 500/ 25
x =20 months
