To find out how many years it will take Cody to collect 577 coins, we can set up the equation based on the information given:
Cody currently has 22 coins. Each year, he adds 15 coins to his collection. We denote the number of years as \( y \). By the end of \( y \) years, his total number of coins will be:
\[
22 + 15y
\]
We want to find out when this total equals 577 coins:
\[
22 + 15y = 577
\]
Now, we can solve for \( y \):
1. Subtract 22 from both sides:
\[
15y = 577 - 22
\]
\[
15y = 555
\]
2. Divide both sides by 15:
\[
y = \frac{555}{15}
\]
\[
y = 37
\]
So it will take Cody **37 years** to collect 577 coins.
The correct equation and solution for this situation is:
**15y + 22 = 577; 37 years**
