To solve this problem, we need to determine the value of x, which represents the number of apples that one child sold.
Let's break down the information given:
Number of children: 5
Number of apples in each bag: 15
Number of apples eaten by 2 children: 2 * 4 = 8
Number of apples sold by one child: x
Total number of apples left: 60
We can set up the equation as follows:
(Number of children * Number of apples in each bag) - (Number of apples eaten by 2 children + Number of apples sold by one child) = Total number of apples left
(5 * 15) - (8 + x) = 60
Let's simplify and solve for x:
75 - (8 + x) = 60
75 - 8 - x = 60
67 - x = 60
To isolate x, we subtract 67 from both sides of the equation:
67 - x - 67 = 60 - 67
-x = -7
Finally, we multiply both sides of the equation by -1 to solve for x:
x = 7
The value of x is 7.
#### 7
The answer is: 7
