Be,
x = number of rental hours
y = The cost of rent
According to the statement, for each rental hour, $3 is charged, so in algebraic language that is: 3x
And in addition to that, $10 dollars is charged, so we have the following amount left
3x + 10
And this sum will result in the rental cost
y = 3x + 10
Answer 1: The linear equation that models the rental cost is: y = 3x + 10
How much does it cost to rent a rowboat for 3 hours?
Let's remember that "x" is equal to the number of rental hours, so substituting x = 3 in the equation y = 3x + 10, we have that
y = 3(3)+ 10 = 9 + 10 =19
Answer 2: Renting a boat for 3 hours costs $19
