Creating and Solving One-Step Equations in Real Life

A baker has 12 cookies and wants to divide them equally into boxes. If each box holds 'x' cookies, how many boxes can he fill? Write an equation to represent this scenario: 12 = x * number of boxes.

• number of boxes = x * 12

• number of boxes = 12 / x

• number of boxes = 12 - x

• number of boxes = 12 + x

Sarah has 20 marbles. She gives 'y' marbles to her friend. Write an equation to find out how many marbles Sarah has left: 20 - y = remaining marbles.

• y = 20 - remaining marbles

• remaining marbles = 20 * y

• 20 + y = remaining marbles

• 20 - y = remaining marbles

A book costs $15. If you have 'z' dollars, how many books can you buy? Write an equation to represent this: 15 * number of books = z.

• number of books = z / 15

• number of books = z + 15

• number of books = 15 - z

• number of books = z * 15

Tom is 5 years older than his sister. If his sister is 'a' years old, write an equation to express Tom's age: Tom's age = a + 5.

• Tom's age = a + 5

• Tom's age = a + 10

• Tom's age = a - 5

• Tom's age = a + 2

A car travels 60 miles per hour. If it travels for 't' hours, how far does it go? Write an equation to represent this: distance = 60 * t.

• distance = 60 * t

• distance = 60 - t

• distance = 60 / t

• distance = 60 + t

Lisa has 'b' balloons. If she buys 8 more, how many balloons does she have now? Write an equation: b + 8 = total balloons.

• b * 8

• b - 8

• b + 8

• b + 5

A farmer has 50 apples. He sells 'c' apples at the market. Write an equation to find out how many apples he has left: 50 - c = remaining apples.

• 50 + c = remaining apples

• c = 50 - remaining apples

• 50 - c = remaining apples

• remaining apples = 50 * c

A movie ticket costs $10. If you have 'd' dollars, how many tickets can you buy? Write an equation: 10 * number of tickets = d.

• number of tickets = d - 10

• number of tickets = 10 * d

• number of tickets = d + 10

• number of tickets = d / 10

A gardener plants 'e' flowers in each row. If he plants 4 rows, how many flowers does he plant in total? Write an equation: total flowers = e * 4.

• total flowers = e * 4

• total flowers = 4 + e

• total flowers = e + 4

• total flowers = e - 4

A school has 'f' students. If 15 new students enroll, how many students are there now? Write an equation: f + 15 = total students.

• f * 15

• f + 15

• f - 15

• f + 10
