Answer:
Step-by-step explanation:
Given
- John's speed = 10 mph
- Brian's speed = 8 mph
- Time 3 hours
Solution
<u>The difference in distance covered:</u>
A is the answer if I calculated right ;)
1. Y= -5/2x + 17/2 (slope intercept form)
2. Y= -3/2x + 13/2 (slope intercept form)
X= number of student tickets soldx+75= number of adult tickets sold
Add the number of student and adult tickets together to total 725 tickets
x + (x + 75)= 725
combine like terms
2x + 75= 725subtract 75 from both sides
2x= 650divide both sides by 2
x= 325 adult tickets
x + 75= 400 student tickets
ANSWER: There were 325 adult tickets sold
Hope this helps! :)
