Answer: the taxi ride will cost $12.25
Step-by-step explanation:
Jacob and his family take a taxi to the airport. The taxi charges $1.75 for each mile. This means that if Jacob travels for x miles, the charge, y in dollars will be x miles times 1.75 which is the charge per mile. It becomes
y = 1.75x
If the distance to the airport is 7 miles, it means that x = 7 and we will substitute it into the equation,
y = 1.75x. It becomes
y = 1.75 × 7 = $12.25
