Question

A student get paid to deliver newspaper after school. She earns $25 a day, plus an extra $0.75 for each newspaper she delivers and $5 for each new customer she signs up for delivery. If d=days, n=newspaper, and c=customers, what function can she use to calculate her earnings?

A) T=25d+n/4+5/c
B) T=25d+3/4n+5c
C) T=25d(3/5n)+5c
D) T=25/d+n+5c

Answer 1

it is b because it has one of the most simple method.

Answer 2

`T=25d+(3)/(4)n+5c`

Explanation:

A student earns a day to deliverer a newspaper= $25

She delivers for d days .

So she earns in d days = $25d

She also earns extra charges for each newspaper = $0.75 =
`(3)/(4)`

If she delivers n newspapers .

So. she earns extra charges for n newspapers =
`(3)/(4) n`

Now we are also given that She earns $5 for each new customer .

If she has c new customers .

So, she earns for c customers = $5c

So, her total earning =
`25d+(3)/(4)n+5c`

Let T denotes the total earning .

So,
`T=25d+(3)/(4)n+5c`

Thus Option 2 is correct.
