Answer 2

can you help me @campbell_st

Answer 3

so direct variation equations are in the form

C = kt k is the constant of variation and needs to be calculated

so you know C = 800 when t = 4

so

800 = k x 4

find k..

Answer 4

i mean B?

Answer 5

that's it

Answer 6

so its B?

Answer 7

correct..B
