Answer 6

test each option, increases by 10 each hour?

use h = 1 and h=2 and see if c(h) increased by 10

Answer 7

c(1) = 10*2(1) - 1 = 19
c(2) = 10 *2(2) - 1 = 39

increased by 20 in 1 hour

Answer 8

c(3) = 10*2(3)-1 = 59

Answer 10

i tested choice A. It said the number of customers increases by 10 per hour.
c(1) = 19
c(2) = 39
