Nationwide Communications offers its customers a monthly plan for text messaging. Customers under this plan pay a flat rate of $5.00 each month for up to 200 text messages. For each additional text message over 200 (up to 2000 messages), the customer will pay $0.10. For each message over 2000 messages, the customer will pay $0.20. Complete the piecewise function that can be used to calculate the monthly billing amount, B, for a monthly level of t text messages. Note: Use the letter t as your variable.

B(t) =

if 0 ≤ t ≤ 200
if 200 < t ≤ 2000
if t > 2000

step-by-step explanation:

my answer is$ 12

step-by-step explanation:

because 15 -2=12

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
