Question

the ramirez family comes home from vacation to find their mailbox overflowing with mail. there are 6 more magazines than there are letters. there are twice as many bills as letters. there are 1/3 as many bills as pieces of junk mail. there are 18 pieces of junk mail. how many magazines are there?

Answer 1

9 magazines

Explanation:

To solve this problem you will want to work backwards. Start with the junk mail. There is 18 junk mail and if there are 1/3 as many bills as junk mail then you will need to multiply 18 * 1/3. This equals 6 bills. If there is twice as many bills as letters then you will need to divide bills(6) by 2 which equals 3. If there are 6 more magazines than letters then you need to add 6 to the letters (3). 3 + 6 = 9
