guess we can average out the extra $60 every two weeks and make it $30 per week. then she makes a total of $300+30=\$330$ per week

anonymous · Answer

so if she works $x$ weeks she will make $330x$ dollars

anonymous · Answer

and you get to solve $6,600\leq 330x\leq 9,900$ for $x$
divide across by $330$ and be done in one step
