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. (1 point)
Let x be the number of pounds of apples Ryan bought.
The cost of the apples is 1.29*x.
So the total cost is 1.29*x + 3.95 = 10.40.
Therefore, 1.29*x = 10.40 - 3.95 = 6.45.
Thus, x = 6.45 / 1.29 = <<6.45/1.29=5>>5 pounds of apples. Answer: \boxed{5}.
To solve this problem, we need to set up an equation to find how many pounds of apples Ryan bought.
Let's assume that Ryan bought x pounds of apples.
According to the problem, the cost of the loaf of bread is $3.95 and the cost of apples is $1.29 per pound.
Therefore, the cost of the apples that Ryan bought can be calculated using the equation:
Cost of apples = Price per pound × Number of pounds of apples
In this case, the cost of the apples is $10.40 - $3.95 (cost of the loaf of bread) = $6.45.
Equating this with the equation above, we get:
$6.45 = $1.29 × x
To solve for x, we can divide both sides of the equation by $1.29:
x = $6.45 / $1.29
Now, let's solve this equation:
x ≈ 5
Therefore, Ryan bought approximately 5 pounds of apples at the grocery store.
Let's assume Ryan bought x pounds of apples.
The cost of the loaf of bread is $3.95.
The cost of the apples is $1.29 per pound, so the total cost of the apples is 1.29 * x = $1.29x.
The total cost of the loaf of bread and apples is $10.40.
Therefore, the equation is $3.95 + $1.29x = $10.40.
Now we can solve for x.
Subtract $3.95 from both sides of the equation to isolate $1.29x:
$1.29x = $10.40 - $3.95 = $6.45.
Divide both sides by $1.29 to solve for x:
x = $6.45 / $1.29.
Using a calculator, we find:
x ≈ 5.
Therefore, Ryan bought approximately 5 pounds of apples.
