Answer:
2 2/3 or 8/3
Step-by-step explanation:
Step by step I am guessing? (Is that what each question is for?)
STEP 1
First we have to find 1/3 of 23:
23/3= 1/3 of 23 
Then:
5/1 = 15/3
STEP 2
Subtract:
23-15= 8/3
8/3 or 2 2/3
 
        
             
        
        
        
Answer:
$4.34 
Step-by-step explanation:
Given the information: 
- The original price: $5
 - Discount : 20% 
 - Tax: 8.5% 
 
We can find out the actual price that Diane bought a bunch of balloons that was marked down 20% is: 
= the original price (100% - discount rate) 
= 5(100% -20%) 
= $4 
- The tax amount she need to pay is: 
 
= The actual price*tax rate 
= $4*8.5%
= $0.34 
=> the total cost of the bunch of balloons : 
The actual price + tax price 
= $4 + $0.34 
= $4.34 
Hope it will find you well.
