Question
When Apple sells their iPads, they increase the price $50 from what it costs them to actually make the iPads. One Apple store sold 10 iPads one day which cost a total of $5000. How much does an iPad cost to actually make?
Hint:
- Hint:
○ Form the eqaution using given information.
○ Take variable value as any alphabet.
○ Take terms with cofficient at one side and without cofficients at another side.
The correct answer is: $450.
- Step by step explanation:
○ Given:
Increase in price= $50.
Total no. of iphone sold = 10
Total cost of iphone = $5000.
○ Step 1:
Let cost of making iphone be x months.
So,
Cost of 1 iphone = cost of making + $50
Cost of 1 iphone = x + $50
Hence,
Cost of 10 iphone = (x + $50 ) 10
Cost of 10 iphone = (10x + 500 )
○ Step 2:
○ As total cost is $5000.
∴ 10x + 500 = 5000
10x = 5000 - 500
10x = 4500
x = 
x = 450
- Final Answer:
Hence, cost of making of iphone is $450.
