WRITE AN EQUATION TO REPRESENT THE SITUATION


Celebrity A has 400 followers on social media and is gaining 75 followers each day. Celebrity B has 1,000 followers on social media, but is losing 25 followers a day.

400 - 75x = 1,000 + 25x

400 + 75x = 1,000 – 25x

400x - 75 = 1,000x + 25

400x + 75 = 1,000x – 25

WRITE AN EQUATION TO REPRESENT THE SITUATION


Peter and his friends are going to play putt-putt. At one location, they can pay $2.00 for rentals plus $7.50 per game. At another location, it would cost $8.00 for rentals plus $6.00 per game.

2 + 7.50x = 8 + 6x

2 - 7.50x = 8 - 6x

2x + 7.50 = 8x + 6

2x - 7.50x = 8 x- 6

A rental car agency charges $30.00 per day plus per mile $0.15. Another rental car agency charges $36.00 per day plus $0.10 per mile. Which equation could be used to determine how many miles would have to be driven in one day for both rental agencies to cost the same amount to rent? 

30 + 0.15x = 36 + 0.10x
30 - 0.15x = 36 - 0.10x
30 + 36 = 0.10x + 0.36x
36 - 30 = 0.36x + 0.10x

At Gamestop you can buy a Xbox One for $150.00 and each game to go with it would cost $24.00. Or, you can buy a Playstation 4 for $180.00 and each game for $20.00. Write an equation to determine how many games would need to be purchased for the cost to be equal?

150x + 24 = 180 + 20x

180 - 150 = 24 x + 20x

150 + 24x = 180 + 20x

150 - 24x = 180 - 20x
