Answer :

The line of best fit for the data is given:

[tex]y=0.755x+11.339[/tex]

Here, x is the number of customers who pay by cash and y is the number of customers who pay by card.

Put x=90 in the above equation to find the number of customers who pay by card when 90 customers pay by cash.

[tex]\begin{gathered} y=0.755(90)+11.339 \\ =67.95+11.339 \\ =79.289 \end{gathered}[/tex]

Thus, option B is correct.
