Question

Chelsea needs to take a taxi home and lives 7 miles away. The taxi company charges $4 plus $1.50 per mile. How much will she pay?

Answer 1

since per mile cost is $1.50 and Chelsea lives 7 miles away. So for 1 mile cose is $1.50 , you can get for 7 mile cost by multiplying 7 with per mile cost that is $1.50, also it says $4 is charged per trip, so add that to the product of 7 and $1.50
