Members of the swim team want to wash their hair. The bathroom has less than 5600 liters of water and at most 2.5 liters of sham

nordsb [41]

Answer:

Yes, the bathroom has enough water and shampoo for all of them.

Step-by-step explanation:

70L+ 60S < 5600

Putting 8 into L and 7 into S, gives:

70(8) + 60(7) = 560 + 420 = 980

That is definitely less than 5600, so water is OK.

Now,

0.02L + 0.01S

Putting 8 into L and 7 into S, gives:

0.02(8) + 0.01(7) = 0.16 + 0.07 = 0.23

That's definitely less than 2.5 liters, so shampoo is OK as well.

Hence, bathroom has enough water and shampoo for them.

the performing arts department put in its spring show on Friday and Saturday nights. the price of a ticket was the same both nig

Galina-37 [17]

Let $p=$ the price of a ticket
Let $c=$ the cost to put on the show

Formula:
(profit) = (ticket price) * (number of people) - (cost to put on show)
We have two equations here:
$500=120p-c$
$400=100p-c$
Solve:
$100=20p$
⇒ $p=5$
⇒ $400=100(5)-c$
⇒ $400=500-c$
⇒ $c=100$

So the price of a ticket is $5, and the cost to put on the show is $100.
