Pls pls pls help

Answer 1

Answer:

They started with 7,142.86 rupees.  They spent 714.29 rupees on food.

Step-by-step explanation:

We know that 30% of their rupees were spent.  That means that 70% of their money is left, which is 5000 rupees.  So:

0.70x = 5000

x = 5000/0.70 = 7,142.86

They had 7,142.86 rupees to start with.  They spent 10% of the total on food.

7,142.86 x 0.10 = 714.29
