Answer:

D

-29

Step-by-step explanation:

Problem 1

In the first hour, the number of bacteria is 22

In the second hour,the number of bacteria is 44

It looks like the formula is some multiple of 22

That means you should pick D

Problem 2

n = 12

a = 15

d = - 4

an= 15 + (n - 1)*d

a12 = 15 + 11*(-4)

a12 = 15 - 44

a12 = - 29

What single discount is equal to a discount of 1/4 off followed by an additional 10% off the sale price?
White raven [17]
Original is 100
1/4 off is 25 off
75 left
10% what's left is 75-7.5=67.5

this was already out of 100

100=67.5=32.5

1/4 off and then 10% off is the same as 32.5% discount
