WILL GIVE MEDAL!

A rectangular garden next to a building is to be fenced on three sides. Fencing for the side parallel to the building costs $80 per foot, and material for the other two sides costs $60 per foot. If $2,400 is to be spent on fencing, what are the dimensions of the garden with the largest possible area?

_______ feet (parallel side)
_______ feet (other sides)

Answer 1

You need to interpret what they gave you into a question lets say the parallel sides are
X
and the other sides are
Y
now each parallel side is $80 per foot so:
80x
now every other side is $60 per foot so:
60y
The total is $2400 so combine all the numbers and equal it to 2400
80x+60y=2400

Answer 2

OK. Should I solve for y?

Answer 3

and x

Answer 4

also there is another equation

Answer 5

How so?

Answer 6

because there is only 3 sides that are going to be accounted for
