Tom is making birdhouses to sell at a farmer's market. Each birdhouse requires 4.5 feet of wood planks to build, and he sells them for $19.75 each. If he has no more than 80 feet of planks to build birdhouses, how much money can Tom earn at the farmer's market?

Respuesta :

Answer: He can earn about $351

Step-by-step explanation:

Divide 80 feet of planks by 4.5 feet

80/4.5 = 160/9

Multiply that by 19.75

= $351
