Question

Matthew earns $.10 for each local newspaper he delivers twice a week. His brother earns $.25 for delivering each Sunday newspaper. They deliver papers to the same number of houses and together they earn $13.95 per week. How many papers does each boy deliver each week? what is the answer?

Answer 1

Matthew delivers 1 and 3.95.Matt's brother delivers a quarter of one.

Answer 2

For this case, the first thing we must do is define a variable.
x: number of newspapers sold per week.
We now write the equation for the total of newspapers.
We have then:

`0.10 (2x) + 0.25x = 13.95`
Rewriting we have:

`0.20x + 0.25x = 13.95 0.45x = 13.95 x = 13.95 / 0.45 x = 31`
For Mattthew we have:

`2x = 2 (31) = 62`
For his brother:

`x = 31`
Answer:
each boy delivers each week about:
Mattthew: 62
His brother: 31
