Answer:
A. 7
Step-by-step explanation:
Insanely Easy
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
Answer: The maximum number of days would be 5 days.
Given :
Two companies offer jane sales position. Company a pays $3,000 per month plus $250 per car sold.. Company B pays 2,500 per month plus $350 per car sold.
To Find :
Which equation could be used to determine the number of cars sold in a month, x, that would result in the same total income from each company.
Solution :
Let, x car are sold for same income.
Mathematical equation of company one :

Mathematical equation of company two :

For same income :

So, for same total income from each company the number of cars sold in a month should be 5.
Hence, this is the required solution.
So many answers possible.
Let us take, by numbers they mean integers.
Now, the product of 379 and 8 is 3032.
Clearly, on the number line, this number is between the numbers 3031 and 3033.
Hence, the exact product of 379 and 8 is between the pair of numbers 3031 and 3033.
Hope this makes sense.
