1. a local pizzeria sold 65 pizzas yesterday.
(a) the owner offers the employees a bonus if the number of pizzas sold increases by 20% today. how many pizzas must the pizzeria sell for employees to receive the bonus? explain your reasoning.
to find the answer, you first need to find 20% of 65. so you add this number, 13, to 65. this will give you the number you need, which is 78.

(b) suppose the actual 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.
