Answer: $19.02
Step-by-step explanation:
First find the sales tax paid. It will be paid on the cost of the meal:
 = 14.20 * 8%
= $1.14
Then find the tip which was done after the sales tax was added:
= 24% * (14.20 + 1.14)
= 24% * 15.34
= $3.68
The total cost is:
= Gross amount + Sales tax + tip
= 14.20 + 1.14 + 3.68
= $19.02
 
        
             
        
        
        
Oh. I thought you meant 3-6, not questions 3 through 6. Sorry :(
        
             
        
        
        
To find this I would use the pythagorean theorem which is:
a^2 + b^2 = c^2 
Since we already know c = hypotenuse, and a side of the shorter sides we can plug them it like this:
11^2 + b^2 = 12^2
121 + b^2 = 144
b^2 = 23
√23 = 4.79
Round:
B. 4.8 would be your answer!

7+5= 12 ones. Or one ten and 2 ones. They made 12.
