Answer 1

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
