The subscriber needs to use 363 minutes in a month in order for the second plan to be preferable
What should be sign between the equations for the second option to be better?
The sign between the equation of the first cell phone plan and the second phone plan must less than for the second option to yield more value
Let x be number of minutes of call
Total cost of first option=0.20x
Total cost of second option=39.95+0.09x
For the second option to be better, its value must be less than that of first option
39.95+0.09x<0.20x
39.95<0.20x-0.09x
39.95<0.11x
39.95/0.11<x
x>363

Answer:
a 166 67/100
b 20 1/4
c 829 77/100
d 664 47/50
e 208 4/25
Step-by-step explanation:
you need to find the common denominator (the number on the bottom) so for the first one when can 10 = 100 if you multiply 10 x 10 you get 100 so multiply the entire fraction by 10 and you will get 10/100 so the equation would be 381 10/100 - 214 43/100 which equals 166 67/100 then just do the same thing for the rest of them
Answer:
13) 71/84
14) 25/24
Step-by-step explanation:
13) 3/7 + 5/12
36/84 + 35/84 --- you need to have a common denominator
71/84
14) 3/8+4/6
9/24+16/24 -- common denominator by LCM
25/24
