The total minutes for last month is 300 + 800 = 1100 minutes.

Step-by-step explanation:

Last month a phone company charged $ 0.07 per minute for the first 300 minutes of calling time and $0.05 per minute for each minute of calling time in excess of the first 300 minutes . For how many minutes of calling time was Bob charged by the phone company last month?1) Last month the phone company charged Bob $21.00 for his calling time that was charged at $0.07 per minute.2) Last month the phone company charged Bob $40.00 for his calling time that was charged at $0.05 per minute.

He called for 300 minutes with $21.00

2) If Bob was charged $0.05 per minute, it means the call was outside the first 300 minutes. He was charged $40.00 for last month at $0.05 per minute. Therefore, he called for:

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
