Question

In May, Bradley bought 48 styrofoam balls and decorated them as toy figurines. In June, he sold 19 figurines. In May, Lupe bought 44 styrofoam balls to decorate, and in June, she sold 21 figurines. Make a matrix that represents all of their May purchases and their June sales? .

Answer 1

Explanation:

Since we have given that

Number of styrofoam balls bought in May = 48

Number of toy figurines sold in May = 19

Number of styrofoam balls bought in June = 44

Number of toy figurines sold in June = 21

So, we need to make a matrix that represents all of their May purchases and their June sales :

So, it is given by

May June

Purchases Sales

Bradley 48 19

Lupe 49 21

Hence, the proper matrix will be

`\begin{bmatrix}48 &19 \\ 49&22 \end{bmatrix}`

Answer 2

Explanation:

Since we have given that

Number of styrofoam balls bought by Bradley in May = 48

Number of toy figurines sold in May = 19

Number of styrofoam balls bought by Lupe in June = 44

Number of toy figurines sold in June = 21

So, we need to make a matrix that represents all of their May purchases and their June sales :

So, it is given by

May June

Purchases Sales

Bradley 48 19

Lupe 49 21

Thus, we can define a 2x2 matrix in which row 1 represents Bradley and row 2 represents Lupe. The columns then represent May and June. To distinguish between purchase and sale, we will show sale by a positive number and sale with negative; therefore the final matrix will be

`\left[\begin{array}{ccc}48-19\\44-21\end{array}\right]`
