Question

isabella buys milk and potatoes at the store.

• she pays a total of $21.40.
• she pays a total of $3.73 for the milk.
• she buys 3 bags of potatoes that each cost the same amount.

write and solve an equation which can be used to determine ( x ), how much each bag of potatoes costs.
answer attempt 1 out of 4
equation: (square)
answer: ( x = square )

Explanation:

Step1: Define the cost of potatoes

Let \( x \) be the cost of one bag of potatoes. Since there are 3 bags, the total cost of potatoes is \( 3x \).

Step2: Set up the equation

The total cost is the sum of the cost of milk and the cost of potatoes. So, \( 3.73 + 3x = 21.40 \).

Step3: Solve for \( x \)

Subtract \( 3.73 \) from both sides: \( 3x = 21.40 - 3.73 \). Calculate the right side: \( 21.40 - 3.73 = 17.67 \). Then divide both sides by 3: \( x = \frac{17.67}{3} = 5.89 \).

Answer:

Equation: \( 3.73 + 3x = 21.40 \)
