a taxi driver charges $2.25 per mile. the driver also charges a one time $12 fee. write and solve an equation to determine how many miles are driven , for the driver to charge $30 total

if x is the number of miles driven, the equation is 2.25x + 12=30. solved: x = 8 miles

Step-by-step explanation:

First, you make the equation. If x is the number of miles, the price per mile would be 2.25 times x or 2.25x. You also have to add the one time fee of $12, so you have 2.25x + 12. Next, you're trying to find x if it costs $30 total so you would have 2.25x + 12 = 30.

Solving,

2.25x + 12 = 30

subtract 12 from both sides

2.25x = 18

divide both sides by 2.25

x = 8 miles

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
