Question

Fran’s Furniture Company charges $0.75 per pound to ship furniture. Write an equation to determine the total cost, c, to ship p pounds of furniture. Use your equation to determine the cost of shipping a 223-pound dresser.

Answer 1

c=p×.75

c=223×.75
c=$167.25

The letter c is used as a "place holder" for the value cost.
The letter p is used as a place holder for the value pounds.
Since the question above gives us the integer value of pounds, we can replace the p with the integer 223 and solve the formula for the only remaining variable c.
