Z roberts, Coop A contractor needs to buy nails to build a
house. The nails come in small boxes and large
boxes. Each small box has 150 nails and each
large box has 450 nails. The contractor bought
twice as many large boxes as small boxes,
which altogether had 4200 nails. Write a
system of equations that could be used to
determine the number of small boxes
purchased and the number of large boxes
purchased. Define the variables that you use to
write the system.
