Answer:

about 36 and 24 liters  

Step-by-step explanation:

    a+b = 60     1

let A multiplied by  10 percent and B multiplied by 35 percent then

  10 a + 35 b = 1500 ( 60 * 25 ) 2

add no. 1 to 2 and multiply no.1  by -10

-10 a+ -10 b = -600

10 a+ 35 b = 1500  adding

then     25 b = 900 then         b = 36 liter

then     a = 24 liter

Answer:

<em>Equation: </em>

<em>HCL + HCL = HCL </em>

<em><u>0.30x + 0.45(50-x) = 0.35*50 </u></em>

<em><u>Multiply thru by 100 to get: </u></em>

<em><u>30x + 45*50 - 45x = 35*50</u></em>

<em><u>-15x = -10*50 </u></em>

<em><u>x = (2/3)50 </u></em>

<em><u>x = 33 1/3 liters (amt. of 30% solution needed in the mixture) </u></em>

<em><u>50-x = 16 2/3 liters (amt. of 45% solution needed in the mixture) </u></em>

cost $12 for adults and 5$ for children .on the first day of the fair 312 tickets were sold for a total of 2204$.How many adults
IrinaVladis [17]

The number of adult tickets and children tickets sold were 92 and 220 respectively

What differentiate adult tickets from children's

The adult tickets can be represented by a while children's ticket is c

The total number of tickets sold which is 312 means the sum of a and c

a+c=312

Total value of adult tickets=a*12

total value of children tickets=c*5

12a+5c=2204

Solve for a in the first equation

a=312-c

substitute for a in the second equation

12a+5c=2204

12(312-c)+5c=2204

3744-12c+5c=2203

3744-2203=12c-5c

1541=7c

c=1541/7

c=220

a=312-220

a=92
