Number of pizza Price (in dollars)

• A. 46 dollars
• B. 56 dollars
• C. 36 $\frac{1}{2}$ dollars
• D. 56 $\frac{1}{2}$ dollars

Answer 1

The correct option is B 56 dollars

The given line plot is


Total price = 8 + 9 + 9 + 9 $\frac{1}{2}$ + 10 +10 $\frac{1}{2}$

= 36 + $\frac{19}{2}$ + $\frac{21}{2}$

= 36 + $\frac{40}{2}$

= 36 + 20 = 56

Hence, she has to pay 56 dollars.
