in the town of balaoan three children namely pepe, juan and jose deliver newspapers. pepe delivers 3 times qs many papers as jpse and juan delivers 13 more than pepe. if the 3 children delivered 496 newspaper how many papers does each deliver?
Answer:
Jose (x) delivered 69 newspapers.
Pepe (3x) delivered 207 newspapers.
Juan (3x + 13) delivered 220 newspapers.
Explanation:
Let x, 3x and 3x + 13 be the newspapers
x + 3x + (3x + 13) = 496
Combine like terms.
7x + 13 = 496
Transpose 13 and change its sign.
7x = 496 - 13
Subtract.
7x = 483
Divide both sides by 7.
7x/7 = 483/7
x = 69
Jose delivered 69 newspapers.
3x
3(69) = 207
Pepe delivered 207 newspapers.
3x + 13
3(69) + 13
207 + 13 = 220
Juan delivered 220 newspapers.
Checking:
x + 3x + (3x + 13) = 496
69 + 3(69) + ((3)(69) + 13) = 496
69 + 207 + 220 = 496
496 = 496
TRUE
