(a) The pizzeria must sell 72 pizzas for employees to receive the bonus.
(b) There was a 10% increase in the sales of pizzas.
Step-by-step explanation:
Given,
Pizzas sold yesterday = 60
(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?
Expected increase = 20% from yesterday
Total pizzas to be sold = Pizzas sold yesterday + expected increase
Total pizzas to be sold = 60+12 = 72
The pizzeria must sell 72 pizzas for employees to receive the bonus.
(b) Suppose the actual number of pizzas sold today was 66. Describe the number of pizzas sold as a percent increase or decrease, rounded to the nearest hundredth.
Old value = 60
New value = 66
Difference = New value - Old value
Difference = 66 - 60 = +6
The positive sign indicates that it is a increase.
Percent increase =
Percent increase =
Percent increase = 10%
There was a 10% in the sales of pizzas.

Answer:
y = (-2) 2^(x+1)
Step-by-step explanation:
Whenever x increases from by 1, y decreases by doubling (the negative value), so the exponent is -2
When x = -1, y = -2.
So the exponential equation (NOT linear) is
y(x) = -2*2^(x+1)
Check:
y(-1) = -2*2^(-1+1) = -2*1 = -2
y(0) = -2*2^(1) = -2*2 = -4
...
y(2) = -2*2^(2+1) = -2*8 = -16
all good.
