Step-by-step explanation:

according to the question expense of car partly constant and partly vary with no. of kilometers

so he expense on car 3200 per 100km which is constant

and then expense varies on with their number of kilometers

so he expense 3800 when he covered 150km

it's mean=100km+50km=3200+600=3800

so on 1st 100km his expense is constant and after 100km expense vary with respect to number of kilometers he travels

if he travels 250km then his expense=100km+150km=3200+3*600=5000
