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 that leaves the first two optioins
ok so what does that represent there, what you just wrote it represents the total cost right?
yes it does
so if Eddie has only 15 dollars to spend then the total cost cannot be greater than 15 correct?
otherwise he would not have enough money
oh so its an inequality not an equation
correct, so the total cost must be less than or equal to 15, so which inequality is it?
what does the less than or equal to sign look like?
correct, so it must be what then?
cost < or = to 15
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
could you help with another one?
close this one and post another one and i or someone else will help you
