Question

The diameter of a tree increases by about 1/8 inch each year. Write an equation that represents x, the increase in the diameter of the tree, in the last y years.

Answer 1

According to the statement, the diameter increases by 1/8 inch each year, which means that the increase of the diameter is given by the number of years times 1/8.

Taking x as the increase and y as the number of years, the equationthat represents x in terms of y is:

$x=\frac{1}{8}y$
