x ----> the number of wrapping paper sold
y ----> the number of magazines sold
we know that
The classes sold 72 items
so
----> equation A
The classes earned $222 for their school
so
----> equation B
Solve the system of equations by graphing

The number of wrapping paper sold was 32 and the number of magazines sold was 40
Answer:
45.367 cm
Step-by-step explanation:
Approximating to a more number of decimal places gives a better estimation of the exact value.
For 45.367 cm, we approximated to three decimal places or five significant figures.
For 43.43 cm, the approximation is done to four decimal places.
Therefore the measurement 45.367cm is more precise because it has a relatively smaller error.
You should use a bar graph because that would work better
