A teacher has 243 pencils. She gives away 67 of them. She places the remaining pencils in equal groups in baskets. Each basket holds 8 pencils. How many baskets does the teacher need for the remaining pencils?

Which equation could be used to solve the problem? Let b represent the number of baskets.

• b = 243 − (67 ÷ 8)

• b = 243 − 67 − 8

• b = (243 − 67) ÷ 8

• b = (243 − 8) ÷ 67
