in 1990 automobile dealership sold certain model car for $14 and 649 cents in 2000 so the same model car for $23 and 609 cents f
1 answer:
The original prize: 14.649
New prize: 23.609
(the years here are not relevant, just to confuse you with more numbers)
the increase is 23.609-14.649=8.960
If we want to know the percentage, we need to know what percentage of the original prize is 8.960.
this is calculated like this:
ti make it into percentage, we multiply by 100%: 61.164%
New prize: 23.609

Answer:
Step-by-step explanation:
To solve this problem, we need to find the linear function. We know that the constant rate of change is -0.5° Celsius per minute. Also, after 60 minutes the temperature was 10° Celsius. So, we have a one point and the slope of the linear function, let's use the point-slope formula
Where the y-intercept is at (0, 40).
Now, we have two points to graph the relation between minutes and Celsius degrees.
Therefore, the room's temperature as a function of time is
Its graph is attached.
