Question

A rectangular bird feeder costs $18.00. A cylindrical bird feeder costs $24.00. The expected cost to keep the rectangular bird feeder filled is $3.00 per week. The expected cost the keep the cylindrical bird feeder filled is $2.00 per week. The equation below models the break-even point.

18 + 3x = 24 + 2x

What does x represent?

Answer 1

X represents the number of weeks, so $3 per week and $2 per week. Hope this helps!

Answer 2

(x) represents number of weeks.

Explanation:

Let the birds feed is given for x weeks.

Then (cost of bird feeder + cost of bird feeder to be filled ) are same in each case, either bird feeder is cylindrical or rectangular.

So (cost of rectangular bird feeder + bird feed for x weeks)

= cost of cylindrical bird feeder + bird feed for x weeks)

Equation will be

18 + 3x = 24 + 2x

Therefore,(x) represents number of weeks.
