The water level in Ricky lake changes at an average of -7/48 inch for 1 year

It means that

In 1 year , the water level changes at \frac{-7}{48} inches

so, we can multiply both sides by 5

In 5*1 year , the water level changes at 5*\frac{-7}{48} inches

In 5 years , the water level changes at \frac{-35}{48} inches

Hence,

the water level change after 5 years is \frac{-35}{48} inches........Answer
