Question 1208699
Let's say the price of a hamburger is {{{x}}}. This means the price of a salad is {{{x+0.10}}}, from the first statement. The cost of the 10 hamburgers and 5 salads is therefore {{{10x+5(x+0.10)=15x+0.5}}}. However, we also have to include the tax and the tip. Doing so gives {{{1.08(15x+0.5)+5=16.2x+5.54}}}. 
Looking at the price range, we know that {{{37.94<16.2x+5.54<=46.04}}}. Subtracting 5.54 from the inequality gives {{{32.4<16.2x<=40.5}}}. Dividing both sides by 16.2 gives {{{2<x<=2.5}}}. Therefore, the price range of a hamburger is between $2.00 and $2.50, not including $2.
