During the first three months of its life, a breed of exotic fish is born with one stripe and then develops two new stripes every five days. What is the number of stripes, s, that the fish has att days after its birth?

1.17+3.99a. you combine the terms with a to create 3.99 and the 1.17 stays because it has no like terms or a variable

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.

None of them would be estimated to be 3.5.
