Well, we know that the total amount is $420, so we can already set one side of the equation. =420. Also, it said that the $420 is (equal to) 7/6b (b for balance).
Now just put it together! 7/6b=420 is your answer.
This appears to be a composite function situation where you find the value of t(x) and sub that in for the x in c(x). If x = 4, then t(4) = 4(4) + 3 and t(4) = 19. Sub that 19 in for x in c(x) to get 2(19) + 5 which is 43. So 43
I think this is right, i don't know for sure though. y=-x+(1)/(3)
