Question

Ted's favorite coffee shop provides internet access to its customers for initial fee of $3 plus 20 cents per minute.
A. How long can he use the internet if his budget is $15?
B. Write an equation in slop-intercept form that represents the relationship between number of minutes,x and the cost of using wireless internet, y.
C. Graph the linear function.

Answer 1

3+20(m) is the formula u would use
so 15-3=12 so u have 12$ left
follow me so far?

Answer 2

yes

Answer 3

then you do $0.20(m) and try to get as close to 12.00 without going over

follow me still?

Answer 4

yes

Answer 5

.20(59 minutes) is $11.80 so 59 minutes is the answer for a.

Answer 6

B. y=.20x+3

do you see how i got this?

Answer 7

yes i got the same thing

Answer 8

okay so now for c.
i may have to graph this out and send you the link is that okay?

Answer 9

ok

Answer 10

.20x +3 is less than or equal to 15

Answer 11

i was getting to that

Answer 12

slope is 1/5

Answer 13

y=1/5x+12 ok thats the formula for the graph

Answer 14

\[.20x + 3\le 15\]

Answer 15

what is that one for

Answer 16

the cost is .20x + 3. It must be less than or equal to 15

Answer 17

He can use the internet for one hour before he exceeds $15

Answer 18

@mertsj you subtracted 3 form 15 so it would have to be \[\le 12\]

Answer 19

What you want to do is graph y = 1/5x + 3. If y is 15, he has used up all his money. And at a y value of 15, x will be 60
