Question

Momma's ice cream shop sells three types of ice cream: soft-serve, chunky, and nonfat. Location I sells 13 gal of soft-serve, 100 gal of chunky, and 30 gal of nonfat ice cream each day. Location II sells 22 gal of soft-serve and Location III sells 60 gal of soft-serve each day. Daily sales of chunky ice cream are 90 gal at Location II and 120 gal at Location III. At Location II, 17 gal of nonfat are sold each day, and 40 gal of nonfat are sold each day at Location III. Write a 3 × 3 matrix that shows the sales figures for the three locations, with the rows representing the three locations.

Answer 1

The three locations are:

Location I

Location II

Location III

These locations represent the rows of the matrix

The types of ice cream represent the columns

Soft-serve Chunky Nonfat

Location I 13 gal 100 gal 30 gal

Location II 22 gal 90 gal 17 gal

Location III 60 gal 120 gal 40 gal

The 3 × 3 matrix that shows the sales figures for the three locations is:

`\begin{bmatrix}{13} & {100} & {30} \\ {22} & {90} & {17} \\ {60} & {120} & {40}\end{bmatrix}`
