Teri goes shopping for some new clothes and then out to lunch with a friend. She spends $32.94 on some shirts, $15.89 for a belt and $19.99 each for two dresses that are on sale. For lunch, Teri has a salad that is $6.95, iced tea for $1.49 and dessert for $3.49. Teri pays 7% sales tax on both her shopping items and lunch. she tips her server 15%. How much has Teri spent all total for the day?
Teri spent $109.59 in total for the day.
To calculate the total amount Teri spent for the day, we'll first find the total cost of her shopping items, including the sales tax, then add the cost of her lunch, including tax and tip.

Shopping items:
 Shirts: $32.94
 Belt: $15.89
 Dresses (2 dresses at $19.99 each): $19.99 * 2 = $39.98
Subtotal for shopping items: $32.94 + $15.89 + $39.98 = $88.81
Sales tax on shopping items (7%): 0.07 * $88.81 = $6.22
Total cost of shopping items with tax: $88.81 + $6.22 = $95.03

Lunch:
 Salad: $6.95
 Iced tea: $1.49
 Dessert: $3.49
Subtotal for lunch: $6.95 + $1.49 + $3.49 = $11.93
Sales tax on lunch (7%): 0.07 * $11.93 = $0.84
Total cost of lunch with tax: $11.93 + $0.84 = $12.77
Tip for server (15%): 0.15 * $11.93 = $1.79
Total cost of lunch with tax and tip: $12.77 + $1.79 = $14.56
Total amount Teri spent for the day: Shopping items total + Lunch total = $95.03 + $14.56 = $109.59
Teri spent $109.59 in total for the day.
Applications of Linear Equations
