To express Juan's monthly cost for purchasing school lunch, we can define a function \( f(x) \) where \( x \) represents the number of school days in a month.
If we assume the cost of lunch is $3.15 per day, the function can be formulated as:
\[
f(x) = 3.15 \times x
\]
In this function:
- \( f(x) \) is the total monthly cost for school lunches.
- \( x \) is the number of school days in the month.
So, for example, if there are 20 school days in a month, you would calculate the monthly cost as:
\[
f(20) = 3.15 \times 20 = 63.00
\]
This means Juan would spend $63.00 on school lunches for that month.
