    A taxi charges a flat rate of $1.50 with an additional charge of $0.80 per mile. Samantha wants to spend less than $12 on a ride. Which inequality can be used to find the distance Samantha can travel?

    • Each ride will cost 1.50 + 0.8x where x is the number of miles per trip.
    • This expression must be less than 12.

    Setup the inequality:
    1.5 + 0.8x < 12

    Subtracting 1.5 from each side of the inequality
    0.8x < 10.5

    Simplifying even more by dividing each side of the inequality by 0.8, we have:
    x < 13.125
