#20# months

Explanation:

Suppose the number of months needed = #x#

Thus, at the end of #x# months, Kenya pays at the first dealer = #$2350+175xx x#

and, at the end of #x# months, Kenya pays at the second dealer = #$2850+150xx x#

Now, these two payments are equal at the end of #x# months

Therefore,
#$2350+175xx x# = #$2850+150xx x#

or, #175x-150x# = #$2850-$2350#

or, #25x# = #$500#

or, #x# = #$500/25# = #20# months
