Question 2
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 fraction of an ounce, find the cost of mailing a letter that weighs 83 grams.
The cost to mail the letter is $\mathrm{\$}$
. (Type an integer or a decimal.)

Step 1 ：First, we need to convert the weight from grams to ounces since the cost is given in ounces. There are approximately 28.3495 grams in an ounce. So, the weight in ounces is $\frac{83}{28.3495}\approx 2.93$ ounces.

Step 2 ：The cost for the first ounce is $0.49.Sincetheweightoftheletterismorethanoneounce,weneedtocalculatethecostfortheadditionalweight.Eachadditionalounceorfractionofanouncecosts$0.27.

Step 3 ：The weight of the letter is approximately 2.93 ounces. Subtracting the first ounce, we have approximately 1.93 ounces left. Multiplying this by the cost per additional ounce, we get $1.93\times 0.27\approx 0.52$ dollars.

Step 4 ：Adding the cost for the first ounce and the cost for the additional weight, we get the total cost to mail the letter. So, the total cost is $0.49+0.52=1.01$ dollars.
