Question

For each birdhouse, Cooper uses 7 pieces of wood and some nails. He uses 3 times the number of nails as pieces of wood for each birdhouse. He sells each birdhouse for $12. If Cooper has lots of wood, but only 89 nails, how much money can he make selling birdhouse?

A. $348
B. $96
C. $48
D. $144

Answer 1

Let's assume the number of pieces of wood Cooper uses for each birdhouse is x.

So, the number of nails used for each birdhouse is 3x.
Considering he has 89 nails, we can form the equation 3x = 89 nails.
Re-arranging the equation, we get x = 89/3 = 29.67.
Since the number of pieces of wood needs to be a whole number, the maximum value for x is 29.
Therefore, the number of birdhouses Cooper can make is 29.
Hence, the total money he can make selling birdhouses is 29 * $12 = $<<29*12=348>>348.
Therefore, the correct answer is option A. $348.
