The total cost, includes the helmet rental, the cost to rent a bike 9b, and the cost of renting a helmet $6.
A linear equation is an equation in which the highest power of the variable is always 1. The standard form of a linear equation in one variable is of the form Ax + B = 0.
Kenny rents a bike and a helmet.
The expression 9b + 6 represents the total cost to rent the bike for b hours, plus the fee for the helmet.
So, Analyzing the expression, we get
9b + 6
9b = Cost to rent a bike for the number of hours
The fee for the helmet = $6
Hence, the total cost, including the helmet rental the cost to rent a bike plus the cost to rent a helmet.
