Final answer:

By substituting x with 100 in the line of best fit equation y = 45 + 2x, we calculate that Gabriella can expect to sell 245 ice-cream cones on the 100th day.

Step-by-step explanation:

The student is trying to predict ice-cream cone sales using a line of best fit equation, which is given as y = 45 + 2x. To find the expected number of cones sold on the 100th day, we can substitute x with 100 in the equation:

y = 45 + 2(100)

y = 45 + 200

y = 245

Therefore, on the 100th day, Gabriella can expect to sell 245 ice-cream cones.
