Cathy pays $25 a month plus $0.05 per text message. she models this with the function c = 0.05x + 25. if the text messaging fee increases to $0.10, what is her new function?
a) c = 10x + 25
b) c = 0.10x + 25
c) c = 0.10x + 0.05
d) c = 0.05x + 0.10

B. C = .10x + 25

Step-by-step explanation: If the original equation uses .05, and that equation is .05x + 25 = C, then increasing it to .10 would mean that the new equation is .10x + 25.

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph
