Answer 2

Given:

Bakery charges 15 per Rs for first 100 cupcakes

Bakery charges 13 per Rs for next 101-150 cupcakes

After 150 cakes bakery charges 10 Rs per cupcakes.

To Find:

Price of 250 cupcakes.

Solution:

let f(x) be price of cupcakes, where x$\geq$0.

f(x) = {  15x ; $x\leq 100$

            15x +13(x-100) ; $x\leq 150$

            15x + 650 + 10( x-150) ; $x\geq 150$ }

Now, For 250 cupcakes i.e. x = 250

f(x) = 15(250) + 650 + 10(250-150)

f(x) = 3750 + 650 + 1000

f(x) = 5400

Hence, cost of 250 cupcakes is 5400 Rupees.
