x+2 (x+2) + 8
------- = ---------------
14 14+9
solve by using cross products
(x+2) * (14+9) = 14*(x+2+8)
(x+2)*23 = 14*(x+10)
distribute
23x+46 = 14x+140
subtract 14x from each side
9x+46 = 140
subtract 46 from each side
9x =94
x = 94/4
x = 10 4/9 cm
Answer:
The answer is: The adult ticket costs $15 and the child ticket costs $10.
Step-by-step explanation:
Let a = the dollar amount of adult tickets and c = the dollar amount for child tickets. The child ticket cost $5 less than the adult ticket. Then:
c = a - 5
The number of adult tickets times the adult cost plus the number of child tickets times the cost for child tickets is equal to the total dollar amount. Set up the equation:
8a + 2c = $140
Substitute:
8a + 2(a-5) = 140
8a + 2a - 10 = 140
10a = 150
a = 150 / 10 = 15, so the adult ticket is $15
Solve for c:
c = a - 5
c = 15 - 5 = 10, so the child ticket is $10
Proof:
8a + 2c = 140
8(15) + 2(10) = 140
120 + 20 = 140
140 =140
