A bookstore had 180 books. On Friday, it sold 90 of the books. On Monday, the bookstore received a new shipment of books to restock its inventory. Now it has 210 books. Which equation can be used to find n, the number of books the store received on Monday?

• 180 - 90 = 90,

  210 + 90 = n

• 180 + 90 = 270,

  270 - 210 = n

• 180 + 210 = 390,

  90 + 390 = n

• 180 - 90 = 90,

  210 - 90 = n

Every Sunday, Ms.Goston tutors 2 students in math at the bookstore and 3 students online. For each tutoring session at the boostore, she charges $24. For each online session, she charges $30. Which set of equations can be used to find m, the amount of money in dollars Mrs. Smith earns from tutoring each Sunday?

• 24 x 2 = 48,

  30 x 3 = 90,

  90 - 48 = m

• 24 x 3 = 72,

  30 x 2 = 60,

  72 + 60 = m

• 24 x 2 = 48,

  30 x 3 = 90,

  90 + 48 = m

• 24 ÷ 2 = 12,

  30 ÷ 2 = 30,

  12 + 2 = m
