Question

13. At the grocery store Ryan bought a loaf of bread and some apples. The loaf of bread cost $3.95 and the apples 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? Set up the problem and solve it.

A.1.29x + 3.95= 10.40, Ryan bought 5 pounds of apples

B.10.40 - 1.29= 3.95x, Ryan bought 6.45 pounds of apples

C.3.95 - 1.29x= 10.40, Ryan bought 5.16 pounds of apples

D.3.95 + 1.29x=10.40, Ryan bought 4 pounds of apples

Answer 1

The correct answer is A.1.29x + 3.95= 10.40, Ryan bought 5 pounds of apples.

Answer 2

Let's set up and solve the problem step-by-step:

Let's assume Ryan bought x pounds of apples.
The cost of the apples would be 1.29x dollars.
The cost of the loaf of bread is $3.95.
The total cost of the apples and the loaf of bread is $10.40.

Therefore, the equation becomes:
1.29x + 3.95 = 10.40

Now, let's solve it:
Subtract 3.95 from both sides:
1.29x = 10.40 - 3.95
1.29x = 6.45

Now, divide both sides by 1.29 to solve for x:
x = 6.45 / 1.29
x ≈ 5

So, Ryan bought approximately 5 pounds of apples.

Therefore, the correct option is A. 1.29x + 3.95 = 10.40, and Ryan bought 5 pounds of apples.

Answer 3

To solve this problem, we need to set up an equation that represents the total amount Ryan spent on the loaf of bread and apples.

Let's assign a variable to represent the number of pounds of apples Ryan bought. Let's say x represents the number of pounds of apples.

The cost of the loaf of bread is given as $3.95.
The cost of the apples is given as $1.29 per pound.

So, the cost of the apples will be 1.29 times the number of pounds Ryan bought, which can be represented as 1.29x.

The total cost Ryan spent on the loaf of bread and apples is given as $10.40.

Putting it all together, we can set up the equation:
3.95 + 1.29x = 10.40

Now, let's solve the equation to find the value of x, which represents the number of pounds of apples Ryan bought.

To solve the equation, we can subtract 3.95 from both sides to isolate the term with x:

1.29x = 10.40 - 3.95

Simplifying the right side gives us:
1.29x = 6.45

Next, we divide both sides of the equation by 1.29 to solve for x:

x = 6.45 / 1.29 ≈ 5

Therefore, Ryan bought approximately 5 pounds of apples.

The correct answer is option A: 1.29x + 3.95 = 10.40, Ryan bought 5 pounds of apples.
