Find the difference between the points (2.7, 5.1) and (3, 4.7) : )

a. 0.05
b. 0.5
c. 5

I would use the distance formula: d=√(x2-x1)^2+(y2-y1)^2
(2.7, 5.1) is the first point and (3, 4.7) is the second point
d=√(3-2.7)^2+(4.7-5.1)^2
d=√(.3)(.3)+(-.4)(-.4)
d=√0.09+0.16
d=√0.25
d=0.5 so B

Hope this helps

Ibelieve the total for the tip could be $21.90
