Jana took her 3 year old niece out for breakfast. The restaurant they went to was having a special where children under 4 received half off of their meal with the purchase of a regular priced meal. Drinks were not included in the special. If Jana’s meal was $10, her niece’s was $6 before the discount, they each had a $1.25 drink, tax was calculated at 8.25%, and Jana tipped the waitress 15% of the total including tax, what did Jana spend in all? Write an equation for this project.

1.0825(10 + 6.00 + 2.50) = total before deduction
1.0825(10 + 2.50) = total with deduction
Which total is used to determine the tip? Some recommend using the larger total.
.15 total = ?
