Q:

While your family is visiting Deep creek lake, you and your mother decide to go boating. The Rangers charge $6.50 per hour in addition to $25.00 deposit to rent a canoe. If you wish to rent the canoe from 12:30 to 3:30 PM, write and solve a linear equation to find the total cost to rent the canoe.

Accepted Solution

A:
The total cost is $43.5 and it is obtained from the equation c = 6.5n + 25Solution:Given that, while your family is visiting Deep creek lake, you and your mother decide to go boating.  The Rangers charge $6.50 per hour in addition to $25.00 deposit to rent a canoe.  If you wish to rent the canoe from 12:30 to 3:30 PM,  We have to write and solve a linear equation to find the total cost to rent the canoe. Now, we know that,total cost = charges + rent fee [tex]\text {Total cost }=\text { number of hours used } \times \$ 6.5 \text { per hour }+\$ 25[/tex]Let total cost be "c" and number of hours rented be "n"[tex]\begin{array}{l}{c=n \times 6.50+25} \\\\ {c=6.5 n+25 \rightarrow(1)}\end{array}[/tex]Now, they used canoe from 12:30 to 3:30, which means 3 hours of timeSo, put n = 3 in (1)  c = 6.5(3) + 25 c = 19.5 + 25 c = 43.5 Hence, the total cost is $43.5 and it is obtained from the equation c = 6.5n + 25
