Given data:
Cost of each lunch: $6.25
One time delivery fee: $3.50 (this is added to the cost of the lunches
n is the number of lunches
y is the cost of ordering n lunches.
Cost of the lunches: multiply the cost of each lunch by the number of lunches: 6.25n
Add the fee to the cost of lunches to get the cost of ordering n lunches:
Expression:
[tex]y=6.25n+\text{3}.50[/tex]
Total cost of delivering 5 lunches (n=5):
[tex]\begin{gathered} y=6.25(5)+3.50 \\ y=31.25+3.50 \\ y=34.75 \end{gathered}[/tex]
Then, the total cost of delivering 5 lunches is $34.75
