Given is Plan A gives 3 nights lodging and 5 boat rides for a total cost of $625.
and Plan B gives 5 nights lodging and 6 boat rides for a total of $960.
Let x be the cost of night lodging and y be the cost of the boat ride.
The given can be written as follows.


Multiply equation 3x+5y=625 by 5 as follows.


Multiply equation 5x+6y=960 by 3 as follows.


Substract equation (2) from equation (1) to compute the value of y.


Solve like terms.

Dividing by 7 into both sides, we get


Hence we get the cost of the boat ride is $35.
Substitute y=35 in 3x+5y=625 to compute the value of y.


Adding -175 on both sides, we get

Solve like terms.

Dividing by 3 into both sides, we get


Hence the cost of night lodging is $150.
Result :
The cost of night lodging is $150.
The cost of the boat ride is $35.
The cost of each boat is $150 and $35.
