(Explain in a detailed way on how you got your answer)

Answer 1

The percent error is 4.17 %

Solution:

To be labeled as a jumbo egg, the egg is supposed to weight 2.5 oz

When Desmond buys a carton of jumbo eggs, the weight of one is 2.4 oz

To find: percent error

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

$\% \text { error }=\frac{\text {approximate value}-\text {exact value}}{\text {exact value}} \times 100$

Here approximate value = 2.5 oz and exact value = 2.4 oz

$\% \text { error }=\frac{2.5-2.4}{2.4} \times 100\\\\\% \text { error }= \frac{0.1}{2.4} \times 100 = 4.17$

Therefore percent error is 4.17 %
