Final answer:
Mr. Leonard ordered 35 red balloons and 25 white balloons for his son's birthday. There were a total of 60 balloons, with 10 more red balloons than white.
Step-by-step explanation:
The task is to determine the number of red and white balloons Mr. Leonard ordered for his son's birthday, given that there were a total of 60 balloons and that there were 10 more red balloons than white balloons. To solve this, let's let the number of white balloons be represented by 'w' and the number of red balloons would then be 'w + 10' since there are 10 more red balloons than white.
Adding the number of red and white balloons gives us the total:
w + (w + 10) = 60
Combining like terms:
2w + 10 = 60
Subtracting 10 from both sides:
2w = 50
Dividing both sides by 2:
w = 25
So, there are 25 white balloons and since there are 10 more red balloons:
25 + 10 = 35 red balloons.
Mr. Leonard ordered 35 red balloons and 25 white balloons for his son's birthday.
