Kathleen makes 144 cupcakes each week. Of these she sales 25 each week and gives away the rest. Write a linear function that represents the number of cupcakes Kathleen has given away over time.

Solution:

Given that,

Kathleen makes 144 cupcakes each week

Of these she sales 25 each week and gives away the rest

To find: Linear function that represents the number of cupcakes Kathleen has given away over time

Let "x" be the number of weeks

Number of cakes given away = 144 - 25 = 119

Thus, number of cupcakes Kathleen has given away over "x" weeks is given as:

f(x) = 119x

Where, f(x) is the number of cupcakes Kathleen has given away over "x" weeks

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
