Answer 1

Answer:

16kg

Step-by-step explanation:

cost=fixed charge+rate of courier service * weight

57=5+3.25×w

Answer 2

Answer:

c) 16 Kg

Step-by-step explanation:

Total cost = price per kg * kg + fixed service charge

57 = 3.25 * kg + 5

57 -5 = 3.25 * kg

52 = 3.25 *kg

kg = 52/3.25

kg = 16
