The water level of a certain lake is at 35 feet. Due to recent storms, the water level is rising at a rate of 3 inches per day. How many days will it take for the lake to reach a level of 40 feet?

Dbc if u do the math and stuff that what i got let me know if i was wrong

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
