An easy one but I don't know whether the result is correct (decimals).
A soccer team wants to celebrate their victory and they decide to go on a trip.
- The team is made up of 20 students
- The trip is 150$ per person.
- The room is 50 dollars per night per person.
They all have paid in total 7.350 dollars. How many days have they been on a trip?
How I approached it
Be it x for the days they've been on a trip. Days = x.
20 (150 + 50x) = 7350
20 * 150 + 20*50x = 7350
3000 + 1000x = 7350
1000x = 7350 - 3000
1000x = 4350
x = 4350/1000 = 4,35 days
My issue is with these decimals. You can't possibly express days in a decimal number. Do I just write the result like x = 4, ignoring the decimals or is there something wrong with the way I approached the problem?
Thanks a bunch
Your approach is fine. As you say, the problem setter should have chosen values that result in a whole number of nights.
