It would be the initial cost of the machine, plus the cost to make each badge so:150+2n. where n is the number of badges.

So the answer for A is?

yanasidlinskiy · Answer

And then from there for Part B it is 120 + 2(20) since it is asked for 20 badge

paki · Answer

hm... see... 
Part A will be...
let x = number of badges
C(x) = cost of making x number of badges
function:
C(x) = 2x + 150

Part B will be...
C(20) = 2(20) + 150
= $190

Part C will be..
2(7) + 170
= $184
