Question

stephen is making curtains for several windows in his aunt's house. he determines that he needs 8.5 yards of fabric for each window. write an equation to represent the number of yards of fabric needed given a certain number of windows

Answer 1

F(n) = 8.5*n yards, where n is the number of windows

Explanation:

Suppose the house of Stephen's aunt has n windows.

Since he needs 8.5 yards of fabric for each window, then he needs 8.5 times n yards of fabric for the n windows.

Call F(n) the yards of fabric he needs for the n windows, then

F(n) = 8.5*n

For example, if auntie's house had 4 windows, then

F(4) = 8.5*4 = 34 yards.

If auntie's house had 6 windows

F(6) = 51 yards.
