<span>Jon used 1.5 kg of apples and 1.5 kg of oranges.
If 1 kg of apples cost $4, then 1.5 kg will cost $6. If 1 kg of oranges costs $6, then 1.5 kg of oranges will cost $9.
$6 + $ 9 is equal to $15 which is the total Jon spent.</span>
Let x = number of apples. y = number of oranges. we have to write the following equation to represent the problem: 4x + 6y = 15 To satisfy the equation, Jon must have used x = 2.25 y = 1 Substituting 4 (2.25) +6 (1) = 15 9 + 6 = 15 answer Jhon used 2.25kg of apple and 1kg of orange to make the salad. Note: Since the problem does not have any other restrictions, there may be several apple and orange combinations that cost $ 15 per salad.
