Question

Renting a canoe on Lake Santeetlah costs $5.00 per hour for each adult and $2.50 per hour for each child. A family of one adult and two children decide to rent a canoe. Which equation represents the relationship between cost for the family in dollars, c , and the time they rent the canoes in hours, t ?

Answer 1

`c=10t`

Explanation:

Renting a canoe on Lake Santeetlah costs

• $5.00 per hour for each adult
• $2.50 per hour for each child.

Let t be the number of hours of renting the canoe, then

renting a canoe on Lake Santeetlah costs

• 
  `\$5.00t` for t hours for one adult
• 
  `\$2.50t` for t hours for one child
• 
  `\$2.50t\cdot 2=\$5t` for t hours for 2 childs

The total cost is

`\$5t+\$5t=\$10t`

If c is the cost for the family to rent the canoe, then

`c=10t`
