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 birdhouses?(1 point) Responses $48 $48 $144 $144 $96 $96 $348 $348
To find the number of birdhouses Cooper can make with 89 nails, we need to divide the number of nails by the number of nails needed per birdhouse, which is 3 times the number of pieces of wood. Since each birdhouse requires 7 pieces of wood, we need 7 x 3 = <<7*3=21>>21 nails per birdhouse.
Then, Cooper can make 89 / 21 = <<89/21=4>>4 birdhouses.
Therefore, he can make 4 x $12 = $<<4*12=48>>48 selling birdhouses. Answer: \boxed{48}.
