Question
Riley is making welcome bags for new students. She has already made 10 bags, and can make 10 bags per day. If there are 120 new students this year, how many days will it take for her to make exactly 120 bags?
Let d be the number of bags Riley makes. Start by writing an expression that represents the total amount of bags Riley makes.
Nice!

To represent Riley having some welcome bags left over after making one for each new student, we need to express that the total number of bags she makes must be greater than 120.
The original equation is:
\[ 10d + 10 = 120 \]
To represent having some bags left over, we can modify this to an inequality:
\[ 10d + 10 > 120 \]
This inequality states that the total number of bags she makes (the 10 she already made plus the 10 bags she makes per day multiplied by the number of days \(d\)) must exceed 120, which means she will have some welcome bags left over after making one for each new student.
So the complete inequality is:
\[ 10d + 10 > 120 \]
