of her entire life Savings are there's A base price
- 00:33
is two Fifty for the ride plus about twenty for
- 00:35
each mile How do we express that In mathematical terms
- 00:39
while looking at the choice is the easiest way to
- 00:42
solve this one is to realize that the two fifty
- 00:44
is a base price and isn't gonna be multiplied by
- 00:47
anything Yes it's there it's going to be added to
- 00:49
whatever the mile cost is and choices bc and the
- 00:53
all have two point five getting multiplied just to be
