Answer:
73.07%
Step-by-step explanation:
Given that,
Actual value of sold cookies = 26
Assumed value of sold cookies = 45
We need to find Gabby's percent error. The percentage error in a value is given by :
Error = ](Assumed value - Actual value)/Actual value]× 100
So,
[tex]\%=\dfrac{45-26}{26}\times 100\\\\=73.07\%[/tex]
So, Gabby's percent error is equal to 73.07%.
