If he drains 1/8 of a gallon in 1/2, the amount he will drain in one hour is twice as much as 1/8.
Mateo will drain 2/8 (simplified: 1/4) of a gallon in one hour.
It was 210 cm.
The function she used is h(t) = 210 + 33t. This is a linear function, since it is of the form f(x) = mx+b. In a linear function, we have the slope, m, which tells us how much the height increases per year, and the y-intercept, b, which tells us how tall it was when we began measuring. Our m value would be 33 and our b would be 210, so the original height was 210.
