Answer 1

$34.92

Explanation:

You want to know the total bill if Bea orders takeout that includes a $3.50 drink, a $9.80 appetizer, and a $13.90 sandwich. 7% tax is charged, and she gives a 20% tip.

Pretax total

The total of the items ordered is ...

$3.50 +9.80 +13.90 = $27.20

Tax

The tax on this amount is ...

0.07 × $27.20 = $1.90

Bea's total with tax is ...

$27.20 +1.90 = $29.10

Tip

If Bea computes her tip on the bill before tax, the amount will be ...

0.20 × $27.20 = $5.44

This would bring her total bill to $29.10 +5.44 = $35.54

If Bea computes her tip on the bill with tax included, the amount will be ...

0.20 × $29.10 = $5.82

This would bring her total bill to $29.10 +5.82 = $34.92

Bea's total bill will be $35.54 or $34.92, depending on how she computes her tip.

Additional comment

Some travel writers will tell you it is common practice in the US to compute the tip as 15–20% of the pre-tax bill ($34.54). Workers in service industries who depend on tips for a living will suggest the tip be computed as 20% of the after-tax bill ($34.92). (This is the amount we put as "Answer:" above.)
