Answer 2

Answer:

d. 19

Step-by-step explanation:

A matrix is an array of rectangular shape which consists of numbers, symbols, or expressions, arranged in rows and columns.

$\begin{bmatrix}28&21&19\\17&24&15\\22&29&17\end{bmatrix}$

$w_{1,3}$ means element in first row third column. First row means Frank and third column means August.

So, the number of lawns mowed by Frank in August is

$w_{1,3}=19$
