Answer:
The answer is below
Step-by-step explanation:
Let x represent the cost of apples, y represent the cost of strawberries and z represent the cost of oranges.
The money used to buy 2 apples, 3 boxes of strawberry, and 4 oranges is represented as:
2x + 3y + 4z = 15.3 (1)
The money used to buy 4 apples, 1 boxes of strawberry, and 2 oranges is represented as:
4x + y + 2z = 10.9 (2)
The money used to buy 5 apples, 2 boxes of strawberry, and 1 oranges is represented as:
5x + 2y + z = 13.7 (3)
Solving equation 1, 2 and 3 simultaneously gives:
x = $1.5, y = $2.5 and y = $1.2
The cost of orange is $1.5, cost of strawberry = $2.5 and cost of orange = $1.2
