Answer:

Explanation:

Step one:

given

expected weight= 28pounds

Actual weight= 25 pound

Required:

percent error

$\delta = \left| (v_A - v_E)/(v_E) \right| \cdot 100\%$

δ= percent error

vA =actual value observed

vE =expected value

δ=25-28/28*100

δ=-3/28*100

δ=0.107*100

δ=10.7%

The percent error is 10.7%
