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.
Answer:
Step-by-step explanation:
This problem can solved just by replacing the given values into the give inequalities. The first inequality:
[tex]70L+ 60S < 5600[/tex]
Refers to the maximum amount of water.
The second inequality:
[tex]0.02L + 0.01S\leq 2.5[/tex]
Refers to the maximum amount of shampoo.
Then, the problem as is there's enough water en shampoo for 8 long-haired and 7 short-haired members, where L is long-haired and S is short-haired. Now, replacing this values in each inequality, we have:
[tex]70(8) + 60(7)=560+420=980[/tex]
Definitely, there's way enough water to 8 long-haired and 7 short-haired, because the maximum is 5600, and they only spend 980.
[tex]0.02(8)+0.01(7)=0.16+0.07=0.23[/tex]
We see that there's enough shampoo too, because the maximum is 2.5, and these people only use 0.23.
Therefore, the bathroom have enough water and shampoo for 8 long-haired members and 7 short-haired members.
