Answer

Explanation:

Step1: Identify the variables

The equation is $y = 4x+10$, where $x$ is temperature and $y$ is number of cyclists.

Step2: Substitute the value of $x$

Given $x = 8$. Substitute $x = 8$ into $y=4x + 10$. So $y=4\times8+10$.

Step3: Calculate the value of $y$

First, calculate $4\times8=32$. Then $y=32 + 10=42$.

Answer:

D. 42
