(a) Lyla visits her father's construction site. A worker tells her that the 10 foot long metal bars he works with weigh
116 pounds each. There are also shorter bars at the site, made from the same metal, that are 2.5 feet long. Lyla wants to
figure out the weight of the shorter bar to see if she can lift one.
Select the equation from the following options that Lyla can use, and determine the weight of the shorter bars.
