Question

Firas needs at least AED 125 for a new puzzle. He already has AED 35 saved. He earns AED 10 for each household chore. Write and solve an inequality to find how many chores he has to do to buy the puzzle. Let c represent the number of chores.

Answer 1

To find the number of chores Firas has to do to buy the puzzle, we need to write and solve an inequality. Firas has to do at least 9 chores to buy the puzzle.

Step-by-step explanation:

To find the number of chores Firas has to do to buy the puzzle, we need to write and solve an inequality. Let c represent the number of chores.

The amount of money Firas has saved is AED 35, and he needs at least AED 125 to buy the puzzle. He earns AED 10 for each household chore.

We can set up the inequality: 10c + 35 ≥ 125.

Solving for c, we subtract 35 from both sides: 10c ≥ 90.

Then, divide both sides by 10: c ≥ 9.

Therefore, Firas has to do at least 9 chores to buy the puzzle.
