Answer: $20.62
Explanation:
Ok so she spent 27.50 and the tax was 10% and the tip was 15%
10% of 27.50=0.1*27.50=2.75
15% of 27.50=0.15*27.50=4.125=4.13 (rounded to the nearest cent)
So the question is asking about without the tax (2.75) or the tip (4.13) so you have to subtract the tax and tip from the total cost (27.50)
27.50-2.75-4.13=20.62
The cost of her dinner without tax or tip is 20.62
