Question

Schaum earns (x4 + 16x) every month. His wife earns (3x4 + 11x) every

month. X represents the number of days they work in a month. What is the
total earnings in a month?

4x^4+ 27x
2x4^4+ 5x
3x4^4+ 176x
59/33

Answer 1

Given:

Schaum's earnings in a month =
`x^4+16x`

His wife's earnings in a month =
`3x^4+11x`

Where x is the number of working days in a month.

To find:

The total earnings in a month.

Solution:

We know that,

Total earnings = Schaum earnings + His wife's earnings in a month

`=x^4+16x+3x^4+11x`

`=(x^4+3x^4)+(16x+11x)`

`=4x^4+27x`

Therefore, the correct option is A.
