If a Cell Phone Company Z charges a flat fee of $15 plus $0.50 per minute, the equation would be y=0.50x + 15, where y represents total amount of money and x represents minutes, how much would it cost for 20 minutes?

Step-by-step explanation:

f a Cell Phone Company Z charges a flat fee of $15 plus $0.50 per minute,

the equation would be y = 0.50x + 15 ..(1)

where y represents total amount of money and x represents minutes

The cell phone charge for 20 minutes = ?

substitute x = 20 in eq(1)

y = 0.50(20) + 15

y = 10 + 15

y = $25

It costs $20 dollars for 20 minutes.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

i got 142 as my answer
