the price to mail letter at the post office is $0.49 for the first ounce and $0.21 for each additional ounce. amrit paid $1.96 to mail his letter. how much did the letter weight

the answer is 8 oz

Step-by-step explanation:

well it says for the first ounce is $0.49 so $0.49 is your first number, then you're trying to figure out how many $.21

2. then to make this easier you subtract $0.49 from $1.96 and that's is $1.47

3. then all you need to do is divide $1.47 By. 21 cents anand you should get 7.

4. but don't forget the $0.49 for the first ounce, then 1 ounce add it to the 7 and It will equal 8 oz in total
