there are 40 people at a picnic there are 4 more children than adults how many of each are there
Let a represent the number of adults. Solve for a.
a + a + 4 = 40
2a + 4 = 40
2a = 36
a = 18
To determine the number of adults and children at the picnic, we'll need to set up a system of equations based on the given information.
Let's assume the number of adults is "x". Since there are 4 more children than adults, the number of children would be "x + 4".
Given that there are 40 people at the picnic, we can set up the following equation:
x + (x + 4) = 40
By simplifying the equation, we can combine like terms:
2x + 4 = 40
Next, we can isolate the "x" term by subtracting 4 from both sides:
2x = 36
Finally, we divide both sides of the equation by 2 to solve for "x":
x = 18
So, there are 18 adults at the picnic. To find the number of children, we can substitute the value of "x" into the equation:
x + 4 = 18 + 4 = 22
Therefore, there are 18 adults and 22 children at the picnic.
