C = amount of folks buying coach tickets
s = amount fo folks buying sleeper car tickets
we know the train had a total of 96 passengers, so, whatever "c" and "s" are
c + s = 96
we know all tickets sold for all 96 passengers was 19994, so, if "c" folks rode coach, each ticket is 114, thus 114*c is how much money was from couch, or 114c
if "s" folks rode the sleeper car, we know each ticket is 295 each, so 295*s is how much money was from the sleeper car
we also know, the total for all tickets is 19994
thus 114c + 295s = 19994
thus
solve for "s", to see how many folks rode coach
what about the sleeper car? well, s = 96 - c
s = amount fo folks buying sleeper car tickets

Question:
Madison and Allie have a goal to read 3,300 pages together by the end of 3rd quarter. Madison reads 50 page every day Allie reads 10 more pages every day than Madison reads. Write and solve an equation to show how many days it will take them to read 3,300 pages
Answer:
It will take 30 days for them to read 3,300 pages
Step-by-step explanation:
Given:
The total number of pages to be read = 3300 pages
Number of pages Madison reads = 50 page every day
Number of pages Allie reads = 1 0 more pages every day than Madison reads
To Find:
Total Number of days needed to read 3300 pages = ?
Solution:
Let the number days they will take be x
then
Number of pages Madison read per day (x) + Number of pages Allie read per day(x) = 3300
(50)x + (50 +10) x = 3300
50x + 60x = 3300
110x = 5500
x =
x = 30
