Answer:
(t stands for total!)
a) 8x + 20 = t
b) 6x + 25 = t
c) The point of intersection (y intercept) in this case represents the minimum cost, if you don't hire the clown and only get the decorations.
d) If you were to have the clown for a very long time, you should use Fun Times Inc, because while their decorations cost $5 more, their clown is cheaper, and if you use the clown hours more than the other company, you will save money! If you only wanted to use the clown for a short amount of time, you should use Party Planners, because their decorations are cheap, so the total cost would be lower.
Step-by-step explanation:
a) x represents the hours you hire the clown for, multiplied by the cost per hour for the clown: $8
b) x represents the hours you hire the clown for, multiplied by the cost per hour for the clown: $6.
c) If you only buy decorations are not the clown (you used the clown for zero hours), the price would start at either $20 or $25 (depending on the company).
d) Pretty much already explained :)
