Question
Erica earned a total of $50,450 last year from her two jobs. The amount she earned from her job at the store was $1,250
more than four times the amount she earned from her job at the college. How much did she earn from her job at the
college?

Answer 1

$9,840

Explanation:

Let the money earned from college be 'x'.

Given:

Total money earned from the two jobs = $50,450

Money earned at the store = 1250 + 4(Money earned at college)

∴ Money earned at the store =
`1250 +4x`

Now, total money earned by Erica is the sum of money earned at store and college. Therefore,

Total money = Money at store + Money at college

`50450=1250+4x+x\\5x+1250=50450\\5x=50450-1250\\5x=49200\\x=(49200)/(5)=\$9840`

Therefore, the money earned by Erica from her job at the college is $9,840.
