2)

a) There are 52 weeks in one year.

Fort night means a peroid of two weeks.

So in this case 26 deliveries in a year.

After 16 weeks supplier increased price of box.

So 8 deliveries ammount = 8*35 = $280

Remaining weeks are 52 - 16 = 36

36 weeks means 18 deliveries.

18  deliveries ammount = 18 * 37.50 = 675

Total ammount = 280 + 675 = $955

b)If the cost of box is $35

Total ammont for 26 fortnight 26*35 = $910

Extra cost $955 - $910 = $ 45
