the Jones family received 19 pieces of mail on November 3. The mail consisted of letters, bills, magazines, and ads. How many letters did they receive if they received five more ads than bills, the same number of letters as magazines, and three more bills than magazines?​

2 letters.

Step-by-step explanation:

Consider the number of bills as x.

Since they recieve "5 more ads than bills" ads is x+5.

And since they recieved "three more bills than magazines," magazines is x-3.

And since they recieved the same number of magazines and letters, letters is also x-3.

bills=x

ads=x+5

magazines=x-3

letters=x-3.

19 pieces of mail = bills +ads + magazines + letters

plug in the information: 19 = x + (x+5) + (x-3) + (x-3)

group the x's and add the numbers: 19 = 4x -1

solve for x:  x=5

We are still not done since x is the number of bills, not letters.

Plug the value of x into "letters = bills-3."

so...

Letters = 5 - 3

Letters = 2.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
