Question

you are working on a math course that has 100 lessons and have already completed 31 of them. you are able to complete one lesson per day. fill in the equation to model the number of lessons, n, you will have completed after d more days. n = ?d + 31

Explanation:

Step1: Analyze the rate of lesson completion

Since you complete 1 lesson per day, the number of lessons completed in \( d \) days is \( 1 \times d \) (because the rate is 1 lesson per day).

Step2: Determine the coefficient of \( d \)

In the equation \( N = [?]d + 31 \), the term with \( d \) represents the number of lessons completed in \( d \) days. Since you complete 1 lesson per day, the coefficient of \( d \) should be 1.

Answer:

\( N = 1d + 31 \), so the value in the box is \( 1 \).
