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, x, the company has to sell in one day to equal its daily cost?

• 1500 + 8x = 12

• 12 + 8x = 1500

• 1500 + 8x = 12x

• 8x = 12x + 1500

Penelope is going to the carnival to ride the rides. It costs $20 to get into the carnival and ride tickets are $0.50 each. Write an equation that represents this scenario if she spends $35 in all.

• .50x + 20 = 35

• .50x = 35

• .50 + 20x = 35 

• .50x - 20 = 35
