Angela and Ryou are painting a room. Angela has 2/1/2 gallons of blue paint and Ryou has half as much white paint. It will take
2/2/4 quarts to cover each wall. If each wall is paonted obly one color, how many walls will be blue and how many will be white? How much paint will be left over
Blue paint - 2/1/2 = 1 gallon White paint - 1/2 gallon 1 wall - 1/4 quart of paint As 1 quart = 1/4 gallon, one gallon of paint is enough to cover 16 walls. the walls can be either white or blue and the leftover will be 1 and 1/4 gallon paint.
Extrapolation is the process by which a value is estimated by using a previously known set of numbers. Interpolation is where a value is estimated between two known values. In this case, if you wanted to predict the value of the y-variable when the x-variable is 15, you would be extrapolating beyond the known data-set.
