First, to rewrite something in scientific notation, we want to move the decimal point a number of times to the right or left to end with a number between 0 and 10. In this case, we want to move the decimal point 7 times to the left to get the number 1.304. In scientific notation, this would be the same as 1.304*10^7.
I hope this helps!

Step-by-step explanation:
Answer: $340
Step-by-step explanation:
To identify the cost of renting the boat for 30 hours, breakdown the 30hours into specific renting hours
i.e 30 hours = (7 hours + 10 hours + 13 hours)
Then calculate each of the renting cost based on the hour breakdown given above
- Since the Cost of renting a fishing boat is $25 per hour for the first 7 hours, then (25 x 7 hours = $175)
- For the $10 per hour for the next 10 hours, then (10 x 10 hours = $100)
- and for $5 per hour for any additional hours. (5 x 13 additional hours = $65)
Now, sum up all of the cost of the hourly breakdown
i.e 30 hours = (7 hours + 10 hours + 13 hours)
= $175 + $100 + $65
= $340
Thus, the cost of renting the boat for 30 hours is $340
