Dear Student,

◆ Answer -

In the end, Ravi has $ 2.70.

● Explanation -

For start, Peter had $1.80 more than Ravi.

p = r + 1.80

When Ravi spends $ 6.30, Peter has 4 times him.

4 (r - 6.30) = p

Substitute, p = r+1.80

4 (r - 6.30) = r + 1.80

4r - 25.20 = r + 1.80

4r - r = 1.80 + 25.20

3r = 27

r = 27 / 3

r = $ 9

In the end Ravi had r-6.80 = 9-6.80 = $ 2.70.

Thanks dear...
