    A cab charges $1.75 for the first mile and $0.25 for each additional mile. Write and solve an inequality to determine how many miles Eddie can travel if he has $15 to spend. $1.75 + $0.25x ≤ $15; x ≤ 53 miles $1.75 + $0.25x ≥ $15; x ≥ 53 miles $0.25 + $1.75x ≤ $15; x ≤ 8 miles $0.25 + $1.75x ≥ $15; x ≥ 8 miles

    ok so does the initial charge of 1.75 depend on how many miles he drives?

    well after the first mile, no it doesnt, so that will not change after the first mile, so you would not multiply the 1.75 by the number of miles right? the number of miles is x

    so that gets rid of the last two options

    you would multiply x by .25?

    so 1.75+.25x=?

    ok so what does that represent there, what you just wrote it represents the total cost right?

    so if Eddie has only 15 dollars to spend then the total cost cannot be greater than 15 correct?

    correct, so the total cost must be less than or equal to 15, so which inequality is it?

    but x, or the numbers of miles he drives, cant be more than 53, the miles it takes to spend all of his money

    correct, and when you solve the inequality for x i assume you will get x <= 53
