(b) The pizzeria sold 85 pizzas yesterday. Suppose the number of pizzas sold today was 60. Determine the percent increase or decrease in the pizzas sold, rounded to the nearest hundredth. Show your work. % (Increase or decrease?)
PLEASE SHOW WORK thank you :D

The difference is 21.21%

work shown below

Step-by-step explanation:

I'm going to first find the difference between both.

85-60=25

Now, we have to find 25% of 85

We don't have to use the formula, we can do this in our brain, like this -

We can see that 25% of 80 = 20, since 25 = 1/4, and 1/4 of 80 = 20, then, there is the 5 part left, how do we find that??? well, 25% of 5 = 1.25, since 1.25x5=5,

So hence, our answer is 21.25

Hi! 29.4118 (decrease) is your answer. My work's below!

- - - - - - - - - - - - - - - - - - - -

Here's a formula for percentages I've used...

(Old # - New #  ) /Old # x 100

- - - - - - - - - - - - - - - - - - - -

In this case, the old number is 85, and the new number (today's pizza number) is 60.

(85 - 60) / 85 x 100 =

(85 - 60 = 25)

25 / 85 = 0.29411764705

0.29411764705 x 100 =  29.411764705

Now, round it to the nearest hundredth.

29.4118  (decrease)

- - - - - - - - - - - - - - - - - - - -

Good luck! :)

hi there!

the answer will be d: 2

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
