Paco's cell phone carrier charges him $0.20 for each text message he sends or receives, $0.15 per minute for calls, and a $15 monthly service fee. paco is trying to keep his bill for the month below $30. which best describes the possible values of t, the number of texts he can send or receive?
a. t can be any real number where 0 ≤ t < 75.
b. t can be any whole number where 0 ≤ t < 75.
c. t can be any real number where 0 ≤ t < 150.
d. t can be any whole number where 0 ≤ t < 150.

B. t can be any whole number where 0<t<75.

Step-by-step explanation:

the answer is d

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
