(a) the owner offers the employees a bonus if the number of pizzas sold increases by 20%
how many pizzas must the pizzeria sell for employees to receive the bonus? explain your reasoning. < < < < < < <
(b) suppose the actual number of pizzas sold today was 60. describe the number of pizzas sold as a percent

(a) They should sell 78 pizzas to receive the bonus
(b) 7.69 % decrease
(a) The number of pizzas the owner wants to see sold is 65 plus 20% of 65
We can calculate 20% of 65 by multiplying the decimal form of 20% (0.2) times 65. That is: . This means that the owner wants to sell 65 + 13 = 78 pizzas today.
(b) If the actual number of pizzas sold was 60, the reality is that the number of pizzas sold decreased (from 65 to 60). We can therefore calculate the percent of decrease as:
We can round this percent number to its nearest hundredth as: 7.69 %
first, you have to multiply 150x2=300
next, you have to add 150+300= 450
there are many solutions.
step 1: simplify both sides of the equation.
step 2: subtract 4x^2+10x-4 from both sides.
step 3: factor left side of equation.
step 4: set factors equal to 0.
x=-5/2 or x=1
