Answer:
a) $985
b) 89 people
Step-by-step explanation:
a) For this problem, we are given n, and we solve for C(n).
C(n) = 400 + 5n
= 400 + 5*117
= $985
b) For this problem, we are given C(n), and we solve for n.
C(n) = 400 + 5n
845 = 400 + 5n
845-400 = 5n
445 = 5n
n = 89 people
4+ x(5)=8.50 (we use 5 hours since the 1st hour is included in the 4 dollars)
4+5x=8.5 subtract 4 from each side
5x = 4.5 divide each side by 5
x=.9
x=$0.90
