Question 29 Math Question need help with

Question

if the cost to mail a letter is 49 cents for mail weighing up to one ounce and 27 cents for each additional ounce or a fraction of an ounce, find the cost of mailing a letter that weighs 88 grams.

Answer 1

Convert the weight of the letter to be mailed, from gms to ozs

88 gms = 3.104 ozs (There are 28.35 gms in an oz)

Thus, at the rate of 49 cents for one oz and 27 for every oz or a fraction thereafter, the cost to mail 3.104 oz would be 49 + (27 *3) = 130 cents = $1.30
