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:

$y=6.25n+\text{3}.50$

Total cost of delivering 5 lunches (n=5):

$\begin{gathered} y=6.25(5)+3.50 \\ y=31.25+3.50 \\ y=34.75 \end{gathered}$
