2. if the trend continues, how many liters of sand would be expected to be moved with 48 wheelbarrows?

1. Eyeballing the data, the best fit will be pretty close to a line between the leftmost point and the rightmost point.

We estimate those points as (4,220) and (28,470)

The point point form for a line joining (a,b) and (c,d) is

(c-a)(y-b) = (d-b)(x-a)

(28 - 4)(y - 220) = (470 - 220)(x - 4)

24(y - 220) = 250(x-4)

24y - 5280 = 250x - 1000

24y = 250 x + 4280

y = (250/24) x+ (4280/24)

Approximately that's,

y = 10.4 x + 178

4th choice, 10.4x + 180

2. For 48 wheelbarrows,

y = 10.4(48)+180 = 679.2

679.2 liters of sand
