Answer 1

Answer:

2-3.

Step-by-step explanation:

1. According to the question he wants to earn more than $4500 .
2. When he had sold 10 laptops at the cost of $425 per laptop then the total amount he earned by selling 10 laptops. $425*10=$4250.
3. Now the total amount which he have to earn. $4500-$4250=$250.
4. And the cost of each smartphone is $125. And the amount more he want is $250.
5. So the total number of smartphones he have to sell. $250÷$125=2.

Note : If he want to have money more than $4500 then he will have to sell more than 2 smartphones.
