A gymnastics center charges a $60 registration fee and $15 per class. Olivia registers to take a class and pays a total of $210. Which equation can be used to determine how many classes Olivia signed up for?  

• 60 - 15x = 210 
• 15x - 60 = 210
• 15x + 60 = 210 
• 210 + 15x = 60

120 more than twice a number is the same as halve a number removed from 8

• 2t+120= ^t/₂ - 8

• 120+2t = ^t/₂ - 8

• 2t+120 = 8 - ^t/₂

• 2(t+120)=8 - ^t/₂

4 times a number increased by 5 is the same as 3 times the difference of a number and 2.  Which of the following equations would find the number?

• 4n + 5 = 3n - 2
• 4n + 5 = 3(n - 2)
• 4n+5 = 3(n + 2)
• 4n + 5 = 3 - 2n

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

If ChipCo sold their bags of corn chips for $5 per bag plus $1 for bagging it and it costs the same as $4 per bag of CrunchyChips corn chips plus their price of $2 for bagging it, what would the equation be and how many bags of chips would make them cost the same?

• 5 + 1x = 2x + 4; 1 bag of chips

• 9x = 3; 3 bags of chips

• 5x + 1 = 4x + 2; 1 bag of chips

• 5x = 6x; -1 bag of chips

Rachel and Sharon are splitting up their Pokemon cards.  Rachel has 4 fewer than 3 times as many as Sharon.  Together they have 100 cards.  Which equation could be used to solve for how many cards Sharon had originally?

• n + (3n - 4) = 100
• n - (3n - 4) = 100
• n + (4 - 3n) = 100
• 4 - 3n = 100
