Answer:
Here we will check the percent changes in the values.
1. Candice buys a board that is 12 feet long. The store incorrectly measures and prices the board at 13.2 feet.
% change = [tex]\frac{13.2-12}{12} \times100=10[/tex]%
2. Leo weighs 10 pounds of dog food at the pet store. The scale mistakenly lists the bag at 11.5 pounds.
% change = [tex]\frac{11.5-10}{10} \times100=15[/tex]%
3. Josie’s odometer says she traveled 24 miles in her car. Her GPS, the more accurate source, says the distance is actually 20 miles.
% change = [tex]\frac{24-20}{20} \times100=20[/tex]%
4. Lenny’s bug collection has a bug that is 16 centimeters long. Lenny fumbles with a ruler and incorrectly reports the bug to be 18 centimeters long.
% change = [tex]\frac{18-16}{16} \times100=12.5[/tex]%
