Problema Solution
The Parker’s are installing a wooden fence in their backyard. They have 330 feet of wood. The length can be no more than 90 feet. Write and solve an inequality to find the maximum width of the fence.
Answer provided by our tutors
you must mean they have 330ft^2 wood (in the text)
l = the length of the fence
w = the width of the fence
the length can be no more than 90 feet
l <= 90
they have 330 ft^2 of wood thus we have
l*w <=330
w <= 330/l

we see that w has maximum when l = 90 thus the maximum of w is
w = 330/9
w = 36.67 ft
