To calculate the total earnings of Bianca at two different profiles, per hour earnings have been given as,
She worked for a combined total of 75 hours for both the jobs this month.
Let c be the number of hours Bianca worked as a content writer.
Her earning for this month as a content writer = $10c
Her working hours as library assistant this month = (75 - c) hours
Therefore, her earning as a library assistant for the month = $14(75 - c)
By adding the earnings as a library assistant and a content writer for the month = $10c + $14(75 - c)
= (10c - 14c) + 1450
= $(9c + 1050)
Therefore, expression for the combined total amount she earned this month will be $(9c + 1050).
