THE COST OF MAINTAINING A CAR IS PARTLY VARIES AS THE NUMBER OF KILOMETERS COVERD.IF THE CAR COVERS 2OOOKM IT COST #35OO.OO TO MAINTAIN IT. IF IT COVERS 1OOOOKM IT COST #95OO.OO TO MAINTAIN IT. FIND THE COST OF MAINTENANCE WHEN AT COVERS 14OOOKM
y = ax+b
eliminating all those useless zeroes, (distance in 1000 km, cost in #100)
2a+b = 35
10a+b = 95
find a and b, and then find
14a+b
