Plz ! i need this answer fast!
a cell phone service provider offers two plans. plan a includes a fee of $25 per month and charges $0.25 for every call. plan b includes a fee of $40 per month and offers unlimited calls. for what number of phone calls is the cost of plan b less than the cost of plan a?
more than 60 calls
more than 160 calls
more than 120 calls
more than 100 calls

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!

unless if u could do my questions, if not i wouldn't want to
