Dallas makes and sells dog toys at a local pet store. He earns $5 for each toy that he sells. He wants to sell enough toys to buy a doghouse for $250. Write an equation that represents the number of toys (t) Dallas must sell to earn $250. 

• 5t = 250
• t ÷ 5 = 250
• t + 5 = 250
• 250 + 5 = t

A repair person charges $25 per hour to do repairs. In addition, the repair person charges a $30 flat-rate fee per repair visit. Which equation represents the total cost, C, of a single repair visit that takes h hours?              

• C + 30 = 25h
• C + 25h = 30h
• C = 25h + 30
• C = (25 + 30)h
