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

Write an equation

John and Mary decide to race. John has a 300 ft head start, and runs at a pace of 250ft per minute. Mary runs at a pace of 400 ft per minute. How long before Mary catches up to John?

• 250 + 300m = 400

• 300m + 400 = 250m

• 250 + 400m = 300m

• 300 + 250m = 400m
