Question

Priscilla decides to order a delivery from the local sandwich shop. Her order comes to $12.74 and there is a $2.30 delivery charge. When the food is delivered, Priscilla adds on to her receipt a charge of 15% of her total, not including the delivery charge, as a tip for the driver. When Priscilla goes to check her debits on her online bank statement, what amount should she expect as her total debit?

Answer 1

If $2.30 is in the 12.74 then her amount is $14.61.
If it is not included, her amount is $17.30.

Answer 2

Answer: $16.95

Explanation:

Given: The cost of order of food = $12.74

Delivery charge = $2.30

Then, the total cost of order =
`\$12.74+\$2.30=\$15.04`

Since, when the food is delivered, Priscilla adds on to her receipt a charge of 15% of her total, not including the delivery charge, as a tip for the driver.

Then the total amount should she expect as her total debit =
`\$15.04+0.15*\$12.74=\$16.951\approx\$16.95`

Hence, the total amount should she expect as her total debit
`\$16.95`
