The cost of staying at a hotel can be found using the function y = 129x + 9.95, where x is the number of days a guest stays at the hotel and y is the cost in dollars. The cost includes a flat fee for Internet access. If the fee for Internet access is not included, which statement is true?
A. The cost is $9.95 less per day.
B. The cost is $9.95 less.
C. The cost is $9.95 more per day.
D. The cost is $9.95 more.
if it is not included, then you subtract it from the total. So, ...
correckit!
To determine the answer, we need to compare the original function, y = 129x + 9.95, with the new function when the fee for Internet access is not included.
In the new function, since the fee for Internet access is no longer included, we need to subtract the flat fee of $9.95 from the original function.
The new function would be y = 129x.
Now we can compare the two functions.
In the original function, for each day stayed (x), the cost increases by $129. Additionally, there is a flat fee of $9.95.
In the new function, for each day stayed (x), the cost increases by $129, but there is no flat fee.
Comparing the two functions, we can conclude that the cost is $9.95 less when the fee for Internet access is not included. Therefore, the correct statement is:
A. The cost is $9.95 less per day.
