Writing and Solving 1 and 2 Step Equations

Lucy rents a bike from a company that charges an initial fee of $12 plus $3 per hour that the bike is rented. If Lucy spends $30, write an equation that can be used to represent how many hours she can rent the bike.

• 3x - 12 = 30

• 3x + 12 =30

• 3x = 30 + 12

• 30 - 3x = 12

You bought a magazine for $5 and four erasers. You spent a total of $25. How much did each eraser cost?  (Define 'n' and write the equation.) 

• n=total cost of erasers; 5 + 4n = 25
• n=cost of 1 eraser; 5 - 4n = 25
• n=cost of 1 eraser; 5n + 4 = 25
• n=cost of 1 eraser; 5 + 4n = 25
