Question

Your home state uses a linear model $y=22(x-70)+4338$ to predict the number of vacationers $\left(y\right)$ as compared to the average temperature for that week $\left(x\right)$. Find the number of vacationers predicted for a week with an average temperature of $68$ degrees.

• A. $7374$ vacationers
• B. $5764$ vacationers
• C. $95,392$ vacationers
• D. $4294$ vacationers

Answer 1

The correct option is D $4294$ vacationers

Linear model is given by $y=22\times (x-70)+4338$
where $x$ is average temperature and $y$ is number of vacationers predicted for a week

putting value of $x=68$ in above equation we get,

$y=22\times (68-70)+4338$

$y=22\times (-2)+4338$

$y=-44+4338$

$y=4294$ vacationers
