Question

A fruit stand sells apples, oranges, and bananas at two locations: Market A and Market B. Matrix S shows the number of pounds of each fruit sold at each market on Saturday. Matrix T shows the sales on Sunday.

Order rows 1 to 3 as apples, oranges, and bananas, and order columns 1 and 2 as Market A and Market B.

S = ⎡⎣⎢120806015010075⎤⎦⎥
T = ⎡⎣⎢10070501209060⎤⎦⎥

Which matrix represents the total sales of each fruit at each location on Saturday and Sunday?

(1 point)

S+T=⎡⎣⎢220150110270190135⎤⎦⎥

S+T=[220270150190110135]

S+T=⎡⎣⎢201010301015⎤⎦⎥

S+T=⎡⎣⎢240170120250170125⎤⎦⎥

Answer 1

Add corresponding entries. S = [[120, 80],[60, 150],[100, 75]] and T = [[100, 70],[50, 120],[90, 60]], so

S + T = [[120+100, 80+70],[60+50, 150+120],[100+90, 75+60]] = [[220, 150],[110, 270],[190, 135]].

So the first matrix is correct.
