The answer is 6 people.
Half of the 12 people in the cafe would be 6 people. You can find half of a number by dividing it by two, or multiplying it by .5
The answer is 120 because when you divide 18/15 you get 1.2 and for % you time 1.2*100 =120
Hope it helps:)
Day One- 2d (d being Day Two)
Day Two- d
Day Three- 5 miles
So the expression would be:
5 + 2d + d
Now, we add together the like terms.
5 + 3d
Hope this helps!
