Problema Solution

Micheal wanted to mail a letter that weighed 10 ounces.The charges for postage was .37 for the first ounce and .23 for each additional ounce. What is the equation to find out what Michael has to pay?

Answer provided by our tutors

Let weight of letter = x ounces

Cost for first ounce = 0.37

Cost for each additional ounce = 0.23

Therefore, total cost is give as

C= 0.37 + 0.23(x-1)

=> C = 0.37 + 0.23x - 0.23

=> C = 0.14 + 0.23x

 

Therefore, cost for 10 ounces

=> C = 0.14 + 0.23*10 = 0.14 + 2.3 = $2.44
