An employee earned a total of $5,568 during his first three months at his new job. His paycheck was the same amount each month. For the next seven months at his job, the employee continued to have the same monthly paycheck. His last two months of the year he received a monthly paycheck that was $250 more than his paycheck had been. How much did the employee make his first year on the job?

Ithink is a. true, but not sure

so, converting firstly the mixed fractions to improper fractions and then "adding".

[tex]\bf \stackrel{mixed}{2\frac{9}{10}}\implies \cfrac{2\cdot 10+9}{10}\implies \stackrel{improper}{\cfrac{29}{10}}~\hfill \stackrel{mixed}{5\frac{4}{15}}\implies \cfrac{5\cdot 15+4}{15}\implies \stackrel{improper}{\cfrac{79}{15}} [-0.35em] ~\dotfill[/tex]

[tex]\bf -\cfrac{29}{10}+\left( -\cfrac{79}{15} \right)\implies -\cfrac{29}{10}-\cfrac{79}{15}\implies \stackrel{\textit{using the lcd of 30}}{\cfrac{-(3)29-(2)79}{30}}\implies \cfrac{-87-158}{30} \cfrac{-245}{30}\implies -\cfrac{49}{6}\implies -8\frac{1}{6}[/tex]
