Clark has to add 577 coins which is 577 - 22 = <<577-22=555>>555 coins
Clark needs 555 / 15 = <<555/15=37>>37 years to complete his collection. Answer: \boxed{37}.
Cody has 22 rare coins. Each year Clark plans to add 15 coins to his collection. How many years will it take Cody to collect 577 coins?
6 answers
can you explain it step by step
Certainly! Here's a step-by-step explanation:
1. Let's assume it takes "x" years for Cody to collect 577 coins.
2. After "x" years, Cody will have 22 + 15x coins. This is because Cody starts with 22 coins and adds 15 coins every year.
3. Setting up the equation: 22 + 15x = 577.
4. Subtract 22 from both sides of the equation to isolate the term with "x": 15x = 577 - 22.
5. Simplify the right side: 15x = 555.
6. Divide both sides of the equation by 15 to solve for "x": x = 555 ÷ 15.
7. Using long division or a calculator, you will find that x ≈ 37.
Therefore, it will take approximately 37 years for Cody to collect 577 coins.
