During his vacation Dylan rents a small boat the cost starts with a flat fee of 30 dollars and 10 dollars per hour with the boat plus including taxes the total tax comes out to 90 dollars how much hours did he spend on the boat
Let x be the number of hours Dylan spent on the boat.
The total cost of renting the boat, including tax, is $30 (flat fee) + $10x (hourly fee) + $90 (tax) = $10x + $120.
Since the total cost is $10x + $120, we can set up the equation:
$10x + $120 = total cost
Since the total cost is unknown, we can't set up an equation to find the total amount Dylan paid.
However, we can determine how many hours Dylan spent on the boat based on the information given. Dylan paid a total of $120 for renting the boat, including tax.
$120 = $30 (flat fee) + $10x (hourly fee)
$90 = $10x
x = 9
Dylan spent 9 hours on the boat.
