The cost of one sandwich is $5.7
<h3>How to determine the cost of one sandwich?</h3>
The given parameters are:
Order = 3
Tax = 8% off
Total cost = $20.66
Tip = $5
The cost of one sandwich is calculated as:
Total cost = Order * Cost of One (x) * (1 - tax) + Tip
This gives
20.66 = 3 * x * (1 - 8%) + 5
Subtract 5 from both sides
15.66 = 3 * x * (1 - 8%)
Make x the subject
x = 15.66/[3 * (1 - 8%)]
Evaluate
x = 5.7
Hence, the cost of one sandwich is $5.7
