Molly owes her brother $300.She works for $10 per hour as a checker at the local grocery store.Molly plans to repay her brother
gavmur [86]

Answer: The expression which represents the condition described is given as  4x=300

Step-by-step explanation:

Since we have given that

Amount that Molly owes her brother = $300

Let the number of hours she worked as a checker be x

Cost of per hour = $10

Amount she get after doing work for x hours is given by

10x

Rate of tax are taken out = 80%

So, amount she left with is given by

\frac{100-20}{100}\times 10x\\\\=\frac{80}{100}\times 10x\\\\=8x

So, Molly plans to repay her brother half of what she earns is given by

\frac{8x}{2}=4x

According to question,

4x=300\\\\x=\frac{300}{4}\\\\x=75\ hours

So, the expression which represents the condition described is given as

4x=300
