Answer 1

A. It is the sum of the initial amount and the additional amount after d days.

Explanation:

Answer 2

A. It is the sum of the initial amount and the additional amount after d days.

Explanation:

We have been given an expression
`100+0.25(d-1)`, which gives the total amount of money in Jennifer's savings account after d days.

Since Jennifer adds $0.25 each day after first day, so amount in Jennifer's account after d days would be 100 plus 0.25 times d minus 1 day.

Since Jennifer "adds" an amount each day, therefore, the expression is the sum of initial amount and the additional amount after d days.
