One way is to type it into your trusty TI and use the table from presing stat and then stat againg then calc then 4
so the equation that I got from your set of points is y=1.983333333333333x+0.80555555555
4 hours for 18
7 hours for 25.50
Difference in hours: 7-4 = 3
Difference in cost: 25.50 - 18 = 7.50
7.50 / 3 = 2.50
A. They charge 2.50 per hour.
B. 2.50 x 4 = 10
18 - 10 = 8
The flat fee is 8 dollars
C. 8 + (2 x 2.50) = 13 dollars
Y=2.50x+20. Plug in values for x starting at 0 and you will get values for y and then graph.
Hello!
To find how many times greater his average is, we just divide.
185.4/122.9≈1.51
Therefore, his average is about 1.51 times greater than Lola's.
I hope this helps!
