James bought 5 apples and 10 oranges for $4. donald bought 3 apples and 9 oranges for $3. the shop keeper strictly told that there will not be any discounts. what is the cost of an apple and an orange?

Let cost of 1 apple i=x dollar

and cost of 1 orange = y dollar

according to question we get following equation

james, 5x + 10y=4 ... (1)

donald, 3x+9y=3 ... (2)

solving 1,2 eq. we get

x=2/5 dollars and y=1/5 dollars
