c = number of children
s = number of students
a = number of adults
since the theater has a capacity of 189, then c + s + a = 189.
there are half as many "a" as "c", so then a = c/2 or 2a = c.
so the cost for all children since the price for one is 5 bucks, the total will be 5*c or 5c.
likewise, the total cost for students is 7*s or 7s.
and for adults likewise is 12*a or 12a.
we know all ticket sales was 1372, so then 5c + 7s + 12a = 1372.
now, let's use the elimination method on that system of equations of two variables, let's multiply hmmmm say the first equation by -7, to eliminate the "s".
Answer:
23.38 inches of fabric was used for headband for each player.
9.43 inches of fabric was used for wristband for each player.
Step-by-step explanation:
Given that:
Total fabric used on headbands = 888.44 inches
Total number of players = 36
Total number of coaches = 2
Total number of people for whom headbands were made = Number of players + Number of coaches = 36 + 2 = 38
Amount of fabric used for each one = Total fabric used for headbands divided by Total number of people
Amount of fabric used for each one =
Similarly,
Total fabric used on wristbands = 339.48 inches
Total number of players = 36
Amount of fabric used for each one = Total fabric used for headbands divided by Total number of players
Amount of fabric used for each one =
Answer:
Constant of proportionality
K= 16.5 gallons per minute
Step-by-step explanation:
Time t (minutes) Water g (gallons)
For t= 1, g= 16.50,
for t= 1.5 ,g= 24.75
For t= 2,g= 33
Let the function be
Gallons g= k(time t)
Where k is the constant of proportionality
16.5= k(1)....for when t= 1
24.75= k(1.5) ..for when t= 1.5
Solving gives
8.25=k(0.5)
8.25/0.5= k.
16.5 = k
K= 16.5 gallons per minute
