Question

l. What is the cost of mailing a package if the rates is 30 cents for each ounce and $1.25 for handling?

2. An architectural plan suggests that the length of an entrance way should be one-fourth the length of the house.

Answer 1

1. Let the total cost = y and let x = number of ounces the package weighs, then:

y=$0.30x + $1.25

 

2. Let y = the length of the entrance way and let x = the length of the house, then:

y=(1/4)x
