A student etudied 4 hours on Friday and 2.5 times as many Saturday what is the correct way to determine how studied both days?

The correct way to determine the total number of hours the student studied both days is to add the number of hours studied on Friday to the number of hours studied on Saturday.

Let x be the number of hours the student studied on Saturday.

According to the given information, the student studied 2.5 times as many hours on Saturday as they did on Friday. So, x = 2.5 * 4 = 10 hours.

Therefore, the total number of hours the student studied both days is 4 + 10 = 14 hours.
