if c=5200+200s, find the total cost to transport 13 tons of sugar

Answer 1

you can just plug in s = 13 directly into the equation and then simplify!

c = 5200 + 200(13)

c = 5200 + 2600

c = 7800

meaning that the total cost to transport 13 tons of sugar is $7800

Answer 2

Substitute 13 for s

C = 5200 + 200 (13) = 5200 + 2600

C = 7800
