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

its a straight line parallel to the time axis

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
