Blind company A charges $25.00 to install blinds for one room and $5.00 for each additional window. Blind company B charges $30.00 to install blinds in one room and $4.00 for each additional window. Write an equation to determine how many blinds would need to be installed for the price to be equal.

25 + 5x = 30 + 4x
25 - 5x = 30 - 4x
30 - 25 = 4x + 5x
25x + 5 = 30x + 4

Carol wants to join a dance studio. Studio A charges $100.00 for the entry fee and $45.00 per class, while Studio B charges $125.00 for the entry fee and $30.00 per class.  Write an equation to determine how many classes would need to be taken for the price to be equal? 

125 - 100 = 45x + 30x
100x + 45 = 125x + 30
100 + 45x = 125 + 30x
100 - 45x = 125 - 30x

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
150 + 24x = 180 + 20x
180 - 150 = 24 x + 20x
150 - 24x = 180 - 20x

Mary has been offered two jobs. Job A has a starting salary of $36,000 and a raise of $1500 every year. Job B has a starting salary of $29,000 and a raise of $2500 every year. Write an equation to determine how many years would Mary's salary be the same at both companies. 

36,000x + 1,500 = 29,000x + 2,500
36,000 - 29,000 = 1,500x + 2,500x
36,000 - 1,500x = 29,000 - 2,500x
36,000 + 1,500x = 29,000 + 2,500x
