The first 10 miles of a taxi ride for free each additional mile cost $0.45 John takes a taxi ride across town and it's a driver $4 write an expression to represent the cost of M miles

Something seems wrong here. Would this mean that, if the ride is only 9 miles, John would not have to pay anything?

To write an expression for the cost of M miles, we need to consider that the first 10 miles are free, and for each additional mile, there is a cost of $0.45.

Let's break down the cost into two parts:
1. The cost of the first 10 miles (which are free)
2. The cost of each additional mile beyond 10

For the first 10 miles, the cost is $0 since it's free.

For each additional mile beyond 10, the cost is $0.45 per mile.

To represent the cost of M miles, we can use the following expression:

Cost(M) = $0.45 * (M - 10)

Here, (M - 10) represents the number of additional miles beyond the first 10.

So, the expression Cost(M) = $0.45 * (M - 10) gives us the cost for M miles in dollars.
