Question

A local pizzeria sold 65 pizzas yesterday. Suppose the number of pizzas sold today was 60. Describe the number of pizzas sold as a percent increase or decrease, rounded to the nearest hundredth. Show your work.

Answer 1

% change formula=
(Old # - New #)/Old # x 100

65= old number
60= new number

% change= (65-60)/65 x 100
= 5/65 x 100
= 0.0769 x 100
= 7.69% change

ANSWER: There was a 7.69% decrease since the number of pizzas dropped from yesterday to today.

Hope this helped! :)
