Since there is a short difference between the starting and ending times, we calculate the schedule of each commercial and then compare the broadcasting times.
Commercials of the broadcast Ramon is watching air at:
7.17, 7.34, 7. 51, 8.08, 8.25, 8. 42 8.59 a.m.
Commercials of the broadcast Justice is watching air at:
7.14 7.28 7.42 7. 56 8.10 8.24 8.38 8.52 a.m.
we can check that there are no matching commercial times.
The commercials will not air on both broadcasts at the same time in the interval 7:00 a.m to 9:00. a.m

Answer:
- 2p +3d = 18.25; 4p +2d = 27.50
- popcorn: $5.75; drink: $2.25
Step-by-step explanation:
a) Let p and d represent the prices of a bag of popcorn and a drink, respectively.
Mohamed's purchase is ...
2p +3d = 18.25
Miguel's purchase is ...
4p +2d = 27.50
__
b) We can subtract half the second equation from the first to get an equation for the cost of a drink.
(2p +3d) -1/2(4p +2d) = (18.25) -1/2(27.50)
2d = 4.50 . . . . . . simplify
d = 2.25 . . . . . . divide by 2
4p +2(2.25) = 27.50 . . . . substitute for d in the second equation
4p = 23.00 . . . . . . . . . subtract 4.50
p = 5.75 . . . . . . . . . divide by 4
The cost of a bag of popcorn is $5.75; the cost of a drink is $2.25.
