pls answer it fast I badly need it ​

Answer 1

Answer:

2a-3b+6ab+5b-2ab+3a =the total amount paid by both of them.

2a+3a-3b+5b+6ab-2ab=total amount paid by both of them

5a+2b+4ab =total amount paid.

When a=100, b=150

5(100)+2(150)+4((100)(150))

=500+300+4(15000)

=500+300+60000

=Rupees 60,800.

Therefore the total amount donated is 60800 rupees
