Question

The cost of metal is proportional to the weight of the metal. Martin buys 12 pounds of metal for $33.00. Create an equation that can be used to determine the cost, in dollars, c, for m pounds of metal.​

Answer 1

Answer: 2.75m = c

Explanation:

First we need to find the unit price

33 / 12: 2.75$ per pound

2.75m = c

We can test if this equation works

2.75(12) = c

33 = c

Which is correct
