Question

Finn is trying to lose weigh. He is exercising and eating right every day. He started out with a weight of 193.9 pounds. Each day, he loses 1.1 pounds. What is his weight after 16.5 days Round to the nearest tenth of a pound.

Answer 1

175.8 pounds

Explanation:

We have that Finn's weight is given by the following function:

`f(x)=193.9-1.1x`

Where x is the elapsed days, then to calculate its weight 16.5 days later, we must replace the value of x, just like this:

`\begin{gathered} f(16.5)=193.9-1.1\cdot16.5 \\ f(16.5)=175.75\cong175.8 \end{gathered}`

Finn's weight after 16.5 days is 175.8 pounds
