The table shows the number of hats made at a factory during three weeks in February.  The number of hats made in Week 4 is represented by n.
The total number of hats made at the factory in February was 2,148,431.  Which equation represents this situation?

• 2,148,431 = (562,937 + 607,822 + 492,375) + n 
• 2,148,431 = (562,937 + 607,822 + 492,375) n 
• 2,148,431 = (562,937 + 607,822 + 492,375) × n 
• 2,148,431 = (562,937 + 607,822 + 492,375) ÷ n 

Mr. Anderson had 185 pieces of wood.  He sold 25 pieces of wood to his neighbor and stacked the rest of the wood into piles around his house.  Each pile of wood contained 40 pieces of wood.  Which equation can be used to find p, the number of piles of wood Mr. Anderson made?

• p = (185+25)+40 
• p = (185−25)−40 
• p=(185+25)×40 
• p=(185−25)÷40

• 70 – a = 126
• a – 70 = 126

At Lincoln Elementary School, the fifth-grade students have a total of 325 pets. Of these pets, 250 are some kind of pet other than cats. Which equation could be used to determine the number of pets that are cats, c?

• 325 + 250 = c
  
• 325 – 250 = c
• 325 × 250 = c
  
• 325 ÷ 250 = c
