The school that micaela goes to is selling tickets to an annual dance competition. on the first day of ticket sales the school sold 7 senior citizen tickets and 8 student tickets for a total of $115. the school took and $40 on the second day by selling 6 senior citizen tickets and one student ticket. what is the price of one senior citizen ticket and one student ticket? show work

a = adult ticket price

s = student ticket price

---

7a + 2s = 87

---

4a + 6s = 74

4a = 74 - 6s  

a = 74/4 - (6/4)s

a = 37/2 - (3/2)s

---

7a + 2s = 87

7(37/2 - (3/2)s) + 2s = 87

7(37/2) - 7(3/2)s + 2s = 87

(259/2) - (21/2)s + 2s = 87

(21/2)s - 2s = (259/2) - 87

(21/2)s - (4/2)s = 259/2 - 174/2

(17/2)s = 85/2

---

s = 85/2(2/17)

s = 85/17

---

s = $5

a = $11

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
