Find x: Calculate Cucumber Price per kg Given $2.8/kg Tomatoes

To solve for the price per kg of cucumbers, follow these steps:

• Step 1: Determine the total cost of tomatoes.
  Given that the cost of tomatoes is 2.8 per kg, and Maggie buys 2 kg, the cost of tomatoes is calculated as:
  \( 2 \, \text{kg} \times 2.8 \, \text{dollars/kg} = 5.6 \, \text{dollars} .

• Step 2: Write the equation for total cost.
  The total cost for tomatoes and cucumbers combined is given as 7.1. Let \( x represent the cost per kg of cucumbers. The equation representing the total cost is:
  $5.6 + 0.6x = 7.1$.

• Step 3: Solve the equation for $x$.
  Subtract the cost of tomatoes from both sides of the equation to find the cost of cucumbers:
  $0.6x = 7.1 - 5.6$.
  Simplifying the right side gives:
  $0.6x = 1.5$.

• Step 4: Isolate $x$ by dividing both sides by 0.6:
  $x = \frac{1.5}{0.6}$.
  Simplify the division to find $x$:
  $x = 2.5$.

Therefore, the value per kg of cucumbers is $x = 2.5$ dollars.
