Q.

100-10m

\newline

Dante's goal this year is to read

100

books. The expression above models the number of books Dante has left to read $m months after the beginning of the year. Based on the expression, how many books does Dante have left to read after

4

months?

\newline

◻

Understand Expression: Understand the expression that models the number of books Dante has left to read. $\newline$ The expression given is $100 - 10m$ , where $m$ represents the number of months after the beginning of the year.
Substitute Value: Substitute the value of $m$ with $4$ months into the expression to find out how many books are left. $\newline$ Number of books left = $100 - 10 \times 4$
Perform Multiplication: Perform the multiplication part of the expression. $\newline$ $10 \times 4 = 40$
Subtract to Find Books Left: Subtract the result from Step $3$ from $100$ to get the number of books left. $100 - 40 = 60$
