A taxi ride costs $3.50 plus $2.50 per mile driven. If Sasha has $37 in cash , what is the greatest whole number of miles she can ride in this taxi ? Happy Holiday ´ s...

Create an equation for the total costs of driving x miles: 3.50 + 2.50x

since Sasha has $37, the equation would become: 3.50 + 2.50x = $37

subtract 3.50 from both sides: 2.50x = 33.50

divide 2.50 on both sides: x = 13.4

since the problem is asking for the greatest whole number of miles, you have to round down and the answer would be: 13 miles.
