A)
i) C(n)=42n
ii)C(n,x)=15n+0.25x
b)She plans to drive a total of 600 Km, therefore: x=600
Budget: C(n)=42n
Deluxe: C(n,x)=15n +0.25(600)=15n+150
Cost of Budget< Cost of Deluxe
42n<15n+150
42n-15n<150
27n<150
n<150/27
n<5.5 ⇒n<5

25:36
Step-by-step explanation:
the number of hours on weekdays which is 25, and the total hours she worked is 25+11 which is 36, so it is 25:36
Answer: y=3/2x
Step-by-step explanation:
First, to find the equation, we can figure out that the cost depends on how many tickets are bought. We can use cost as our y and # of tickets as our x.
An equation in slope intercept form is as follows:
y=mx+b
To get our slope, we must figure out the relationship between the cost and the number of tickets, or the y and the x.
We can use the slope formula,
, to find the slope, m.
= 
Thus, the slope of the equation is 3/2, making our final equation be y=3/2x.
