Jenny receives 30% of a sum of money. The rest of the money is then shared equally between karen and rina. If rina receives $76.65, what is the total sum of money shared by the 3 girls?

Answer 1

Let the total sum of money be x.

Jenny receives 30% of x, which is 0.3x.
The rest of the money is 0.7x.
This 0.7x is shared equally between Karen and Rina, so each receives 0.35x.

Given that Rina receives $76.65, we can set up the equation:

0.35x = 76.65

Solving for x:

x = 76.65 / 0.35
x = 219

Therefore, the total sum of money shared by the 3 girls is $219.
