Question

Nayeli bought snacks for her team's practice. She bought a bag of chips for $3 and a 10-pack of juice bottles. The total cost before tax was $9.70. Write and solve an equation which can be used to determine x, how much each bottle of juice cost.​

Answer 1

To determine the cost per juice bottle, Nayeli's total expense of $9.70 for the bag of chips and the 10 juice bottles was used to set up the equation 3 + 10x = 9.70. Solving for x yields a cost of 67 cents per bottle of juice.

Step-by-step explanation:

Nayeli is calculating the cost of snacks for her team's practice, and we need to find out how much each bottle of juice cost. To solve this, we will use a simple algebraic equation based on the information provided.

Let's call the cost of each juice bottle x. Since she bought a 10-pack of juice bottles, the total cost for the juice will be 10x. We are given that the bag of chips cost $3 and the total cost before tax was $9.70.

Now, we can set up the equation: 3 + 10x = 9.70. To find the value of x, we subtract 3 from both sides to get 10x = 6.70. Next, we divide both sides by 10 to isolate x, giving us x = 0.67.

Thus, each bottle of juice costs 67 cents.

Answer 2

Answer: Each bottle of juice costs $0.67

Step-by-step explanation: To determine the cost of each bottle of juice, we can start by setting up an equation based on the given information. Let's assume that each bottle of juice costs x dollars. The total cost of the chips is $3, and the total cost of the juice bottles is 10x dollars (since there are 10 bottles in the pack and each bottle costs x dollars). The total cost before tax is $9.70, so we can set up the equation: 3 + 10x = 9.70 To solve this equation, we need to isolate the variable x. First, subtract 3 from both sides of the equation: 10x = 9.70 - 3 10x = 6.70 Next, divide both sides of the equation by 10 to solve for x: x = 6.70 / 10 x = 0.67.
