To determine how many pounds of apples Ryan bought, we need to set up the equation correctly.
Let \( x \) represent the number of pounds of apples. The cost for the apples is given as $1.29 per pound. Therefore, the total cost for the apples would be \( 1.29x \).
The total amount Ryan spent on both the loaf of bread and the apples is $10.40. The loaf of bread costs $3.95. So, we can set up the equation:
\[
1.29x + 3.95 = 10.40
\]
Now, let's solve for \( x \).
1. Subtract $3.95 from both sides:
\[
1.29x = 10.40 - 3.95
\]
\[
1.29x = 6.45
\]
2. Now, divide both sides by $1.29:
\[
x = \frac{6.45}{1.29}
\]
Calculating that gives:
\[
x = 5
\]
Thus, Ryan bought **5 pounds** of apples. The correct response is:
**1.29x + 3.95 = 10.40, Ryan bought 5 pounds of apples**.
