Answer:
Step-by-step explanation:
Apply sum of cubes formula: 
4.5 times 10^10
1. Multiply 5times ten to the third
2. Multiply 9 times ten raised to the seventh
Then multiply them together
5000 times 90000000
I'm assuming the problem is nine to the third power divided by nine to the ninth power, so the answer would be 0.000001882. Fraction form would be 1/531441.
Sorry about the first answer, I read the problem wrong.
In order for you to understand this question you have to know what the unit rate is. In order to find it you divide 75 by 3 which is 25 so you know that 1 ticket will cost 25$ so then you multiply that 25 times 5 to get your final answer which is 125.
