To find out how many months it will take for Savings Account A and Savings Account B to have the same balance, we can set up equations based on their current balances and monthly interest earnings.
1. **Account A:**
- Current balance: \( 5200 \)
- Monthly interest: \( 18 \)
After \( t \) months, the balance for Account A will be:
\[
A = 5200 + 18t
\]
2. **Account B:**
- Current balance: \( 4750 \)
- Monthly interest: \( 32 \)
After \( t \) months, the balance for Account B will be:
\[
B = 4750 + 32t
\]
We want to find the number of months \( t \) where both balances are equal:
\[
5200 + 18t = 4750 + 32t
\]
Now, we can solve for \( t \):
1. Rearranging the equation gives:
\[
5200 - 4750 = 32t - 18t
\]
\[
450 = 14t
\]
2. Dividing both sides by 14 gives:
\[
t = \frac{450}{14} \approx 32.14
\]
To the nearest month, it will take approximately \( 32 \) months for both accounts to have the same balance.
Thus, the answer is:
\[
\boxed{32}
\]
