Interpolation equation
Poit 1: (a,b)
Point 2: (c,d)
Intermediate point (x,y)
(d - b)/(c - a) = (y - b) / (x - a)
(a,b) = (2, 4.2)
(c,d) = (4, 5.6)
x = 3
(5.6 - 4.2) / (4 - 2) = (y - 4.2) / (3 -2)
y = [1.4/2]*[1] + 4.2
y = 0.7 + 4.2 = 4.9
Answer 4.9 miles
The way she put it implies that she will sell many water bottles and only one iced tea. the correct equation would be 1.25x+1.49y=100, as she may sell different amounts of each.
He spends 30 to enter and 4 per ride
y = 4x + 30....with x being the number of rides and y being the total cost
