A toy company spends $1500 per day for factory expenses plus $8 to make each teddy bear.  They sell the teddy bears for $12 a piece.  Which equation could be used to find the number of bears t the company has to sell in one day to equal its daily cost?

• 1500 + 8t = 12

• 12 + 8t = 1500

• 1500 + 8t = 12t

• 8t = 12t + 1500

Solve for x:

 $-\frac{4}{3}x+17=-11$  
 $x=?$  

A truck can be rented from Company A for ​$50 a day plus ​$0.70 per mile. Company B charges ​$20 a day plus ​$0.80 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.

At ____?_____ miles, the rental costs are the same.

Solve for x: 0.7 (2x - 4) = 42
