Writing equations w/ variable on both sides

The Frederick County Fair costs $15.00 to get in and $2.50 per ride, while the Montgomery County Fair costs $10.00 to get in and $3.00 per ride. Which equations could be used to determine how many rides you would need to go on for both fairs to be of equal value?

• 15x + 2.5 = 10x + 3

• 15 - 2.5x = 10 - 3x

• 15 + 2.5x = 10 + 3x

• 15 - 10 = 2.5x + 3x

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

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. What equation represents this situation?

• 30+0.15x=36+0.10x

• 30x+0.15=36x+0.10

• 30-0.15x=36-0.10x

• 30x-0.15=36x-0.10

I can join video club A for $25.00 and rent videos for $1.00 each. Or, I can join video club B for $15.00 and rent videos for $2.00 each.What equation represents this situation?

• 25x-1=15x-2

• 25x+1=15x+2

• 25-1x=15-2x

• 25+1x=15+2x

Taxi company A charges $8.00 to get into the cab and $0.75 per mile. Taxi company B charges $6.00 to get into a cab and $1.25 per mile. What equation represents this situation? 

• 8-0.75x=6-1.25x

• 8+0.75x=6+1.25x

• 8x+0.75=6x+1.25

• 8x-0.75=6x+1.25

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. What equation represents this situation?

• 36,000+1500x=29000+2500x

• 36,000-1500x=29000-2500x

• 36,000x+1500=29000x+2500 

• 36,000x-1500=29000x-2500 

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. What equation represents this situation?

• 100+45x=125+30x

• 100-45x=125-30x

• 100x+45=125x+30

• 100x-45=125x-30 

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. Which equation matches the situation?

• 25+5x=30+4x

• 25x+5=30x+4 

• 25-5x=30-4x 

• 25x-5=30x-4
