Answer:
C. 37.5 minutes
Step-by-step explanation:
You can set up a proportion to help you figure this out.
12/15=30/x (in this proportion, the number of laps are both on the numerator and the time it takes her is on the denomiator.)
Now, just cross multiply and your equations should be: 12·x=15·30, which equals to 12x=450.
Divide 12 on both sides and x=37.5
The price y is a function of x, the speed of the processor.
In function notation this means, y=f(x), where f(x)=<span>101x + 207.85.

For example to calculate the (approximate) price of a laptop with processor 4 gigahertz, we let x=4, and plug in f.
That is the price y for x=4 is calculated by y=f(4).
So, since y=f(x)=<span>101x + 207.85, the (expected) price of a laptop with processor speed 2.5 gigahertz is :
y=f(2.5)=101(2.5)+207.85= 460.35 ($)
