Answer 1

Correct question:-

Lakshmi bought a bread for (7x+9) and butter for (3x-5). She gave ₹100. How much will she get back.

_____________________________________

Answer:-

Cost of bread= ₹(7x+9)

Cost of butter= ₹(3x-5)

Total cost= 7x+9+3x-5

7x+3x+9-5

₹10x+4

So total money= ₹100

Money returned= 100-(10x+4)

100-10x-4

$so \: the \: money \: returned = - 10x + 96$
