Question

Nadine is trying to develop a habit of reading more. She starts by reading 30 minutes each day, and increases that amount by 2 minutes per day. The time, t, that she reads on a given day, d, can be represented with the equation t=30+2d.

Answer 1

To find the amount of time Nadine spent reading after the given number of days, we can use the equation \( t = 30 + 2d \).

Let's calculate the time spent reading for each day in the table:

1. **For \( d = 3 \)**:
\[
t = 30 + 2(3) = 30 + 6 = 36 \text{ minutes}
\]

2. **For \( d = 5 \)**:
\[
t = 30 + 2(5) = 30 + 10 = 40 \text{ minutes}
\]

3. **For \( d = 7 \)**:
\[
t = 30 + 2(7) = 30 + 14 = 44 \text{ minutes}
\]

Now we can fill in the completed table:

| d, number of days | t, time spent reading |
|-------------------|-----------------------|
| 3 | 36 |
| 5 | 40 |
| 7 | 44 |
