Answer

Explanation:

Step1: Identify the variables

The equation of the line of best - fit is $y = 0.755x+11.339$, where $x$ represents the number of customers paying by cash and $y$ represents the number of customers paying by card.

Step2: Substitute the value of $x$

We are given that $x = 90$. Substitute $x = 90$ into the equation $y=0.755x + 11.339$. $y=0.755\times90+11.339$

Step3: Calculate the value of $y$

First, calculate $0.755\times90 = 67.95$. Then, $y=67.95 + 11.339=79.289\approx79$.
