Percent error is given by formula
[tex] Percent \; Error = \frac{Measured \; value}{correct \; value} \times 100 \% [/tex]
Error calculation for Amanda:
Accurate measurement value of the top of desk = 80 cm
Measured value by Amanda = 82.4
Error = 82.4-82 = 2.4
Now plug these values to find the percent error.
[tex] Percent \; Error \; of \; Amanda = \frac{2.4}{80} \times 100 \% = 0.03 \times 100 \%= 3 \% [/tex]

Error calculation for Dwayne:
Accurate measurement value of the cabinet = 137.2 cm
Measured value by Dwayne = 140
Error = 140-137.2= 2.8
Now plug these values to find the percent error.
[tex] Percent \; Error \; of \; Dwayne= \frac{2.8}{140} \times 100 \% = 0.02 \times 100 \%= 2 \% [/tex]
3% is clearly more than 2%.
Hence final answer will be:
Amanda has greater percent error than Dwayne.
