4)

Justin

Cars: 140 x 7 = 980

Trucks: 130 x 2 = 260

Vans: 180 x 6 = 1,080

Bonus:  980 + 260 + 1080 = 2320

Sydney

Cars: 140 x 5 = 700

Trucks: 130 x 8 = 1040

Vans: 180 x 4 = 720

Bonus: 700 + 1040 + 720 = 2460

Timothy

Cars: 140 x 10 = 1400

Trucks: 130 x 0 = 0

Vans: 180 x 2 = 360

Bonus: 1400 + 360 = 1760

Step-by-step explanation:

1. means element present at the intersection of second row and first column, which is $130.

2. means element present at the intersection of third row and second column, which is 0.

3.

Number of vehicles sold by Sydney = 5 + 8 + 4= 17

4.

Bonus of Justin

= 7*140 + 2*130 + 6*180

= 980 + 260 +1080

= $2320

Bonus of Sydney

= 5*140 + 8*130 + 4*180

= 700 + 1040 + 720

= $2460

Bonus of Timothy

= 10*140 + 0*130 + 2*180

= 1400 + 0 + 360

= $1760

Hence, Sydney had highest bonus.
