At the grocery store, Ryan brought a loaf of bread and some apples. The loaf of bread cost $3.95 and the apple cost $1.29 per pound if Ryan spent $10.40 for the loaf of bread and apples how many pounds of apples did he buy?

Let the number of pounds of apples Ryan bought be x.

The cost of the apples is 1.29x.
The cost of the loaf of bread is $3.95.
The total cost is 1.29x + 3.95.
The total cost is also $10.40.
Therefore, 1.29x + 3.95 = 10.40.
Subtracting 3.95 from both sides of the equation gives 1.29x = 6.45.
Dividing both sides by 1.29 gives x = 5.
Thus, Ryan bought 5 pounds of apples. Answer: \boxed{5}.

To find the number of pounds of apples Ryan bought, we need to subtract the cost of the loaf of bread from the total amount spent at the grocery store.

So, total amount spent - cost of the loaf of bread = cost of the apples

$10.40 - $3.95 = $6.45

Next, we can calculate the number of pounds of apples by dividing the cost of the apples by the price per pound:

$6.45 ÷ $1.29 per pound = 5 pounds of apples

Therefore, Ryan bought 5 pounds of apples.

To determine the number of pounds of apples Ryan bought, we can use the information provided. We know that the loaf of bread cost $3.95, and the total cost of the loaf of bread and apples was $10.40.

Let's start by subtracting the cost of the loaf of bread from the total cost of $10.40:
$10.40 - $3.95 = $6.45

This means that $6.45 is the amount Ryan spent on apples. We also know that the apples cost $1.29 per pound.

To find the number of pounds of apples, we need to divide the amount Ryan spent on apples ($6.45) by the cost per pound ($1.29):

$6.45 ÷ $1.29 = 5

So, Ryan bought 5 pounds of apples.
