A kayak rental costs $10 deposit and $20 each hour. Write and use an algebraic expression to find the cost of a kayak rental for 6 hours.

Let's represent the total cost of a kayak rental for 6 hours using an algebraic expression.

First, we need to calculate the amount paid for the deposit, which is $10.

Next, we need to calculate the amount paid for each hour of rental. Since the kayak rental costs $20 per hour, we need to multiply the number of hours (6) by the cost per hour ($20).

Therefore, the total cost of a kayak rental for 6 hours can be represented by the algebraic expression:
10 + 20 * 6

Simplifying the expression:
10 + 120

The cost of a kayak rental for 6 hours is $130.

To find the cost of a kayak rental for 6 hours, we can use the following algebraic expression:

Total cost = Deposit + (Hourly rate * Number of hours)

Given that the deposit is $10 and the hourly rate is $20, we can substitute these values into the expression:

Total cost = $10 + ($20 * 6)
= $10 + $120
= $130

Therefore, the cost of a kayak rental for 6 hours would be $130.
