six friends all use $2-off coupons to buy themselves movie tickets. they spend a total of $42. what is the price of one movie ti
MaRussiya [10]

So if six friends each use $2-off coupons, that would be 12 off of the 42, so 30. Then divide that by the 6 and you get $5 each. At least, I think so. Please don't hate me if that's wrong.

If all of the people that live in your home bought one 360 pound hamburger from Mallie’s Sports Grill and ate 2/3 pound servings
Vsevolod [243]
We have 4 people in our home
so total bought 360 pounds of hamburger
each ate 2/3 pound every day
so 360-(amount eaten per day) times (number of days)=0 (0 because we want it to be gone)
number of days=x unknown
amount eaten per day=(number of people) times (amount eaten per person per day)
amount eaten per day=4 times 2/3 lb=8/3
360-8/3 times x=0
360-8/3x=0
add 8/3x to both sides
360=8/3x
multiply both sides by 3/8
1080/8=x
135=x
it would take 135 days or about 4 months or 1/3 year, assuming that my family doesn't get tired of it and that my reletives don't visit and take a whole bunch to bring home.

4 people takes 135 days
