Answer:
it would take 20 months and it would cost $6450
Explanation:
in order to solve this question we need to equate the amount at each dealer against one another
Find the number of months
make the months as an unknown variable (x)
2450 + 200x = 2950 + 175x
now make x the subject of formula
200x - 175x = 2950 - 2450
25x = 500
x = 500/25
x = 20
the amount would be the same in 20 months
to find the amount it would be after those months
replace x with 20
2450 + 200 (20) = 6450
$6450
