20( -1.5r + 0.75)
Multiply everything by 20
= -30r + 15
113.25 because the middle ground of 1 - 150 students is 75 and then 1+150=151 2+149+151 but instead of doing that again and again just multiply the lowest number and the highest number by the middle ground

Step-by-step explanation:
Maximum weight = 20 kg
Bag 1 = 3.5kg
Bag 2 = 15 kg
Bag 3 = 2kg
Bag 4 = 1.5kg
Total weight of bags = 22 kg
Excess weight of his luggage = Total weight of bags - Maximum weight
= 22 kg - 20 kg
= 2 kg
Express the excess weight as a percentage of his maximum weight allowed = excess weight / maximum weight × 100
= 2/20 × 100
= 0.1 × 100
= 10%
Express the excess weight as a percentage of his maximum weight allowed = 10%
