Answer 1

heya user ⭐

Let the no.of girls be x
Let the no.of boys be y

x+y =150-----------------1
50x+25y =5000---------2

Multiply 1 by 50
50x+50y=7500-----------3

subtract 2 from 3
50x+50y=7500
50x+25y =5000
25y=2500
y=100

therefore no. of boys = 100

hope it helps ⭐

Answer 2

Answer:

Explanation:

Let the number of girls be x

Let the number of boys be y

x + y =150  = equation 1

50x+25y =5000 = equation 2

Multiply 1 by 50

50x+50y=7500 = equation 3

subtract 2 from 3

50x+50y=7500

50x+25y =5000

25y=2500

y=100

hence the number of boys = 100
