Miriam David · Answer 1

100 * (1 + r * t)

Step-by-step explanation:

We have that the account balance can be represented by 100 + 100 * r * t, now, to factor the above, the only option we have to find is the common factor of both terms, which is 100.

Therefore, it would remain:

= 100 + 100 * r * t

= 100 * (1 + r * t)

After factoring the function that would be 100 * (1 + r * t)
