karen exchanged BDS$ two thousand dollars and received EC$ two thousand seven hundred calculate the value of one BD$ in EC$

I would just like the formula so i can work it out please

Use a proportion. Cross multiply and solve for x.

2,000/2,700 = 1/x

To calculate the value of one Barbadian Dollar (BD$) in East Caribbean Dollar (EC$), you can use the formula:

Value of 1 BD$ = Amount of EC$ received / Amount of BD$ exchanged

In this case, Karen exchanged BD$ 2000 and received EC$ 2700. Plugging these values into the formula we get:

Value of 1 BD$ = 2700 EC$ / 2000 BD$

Dividing 2700 by 2000, we find that the value of one Barbadian Dollar in East Caribbean Dollar is:

Value of 1 BD$ = 1.35 EC$

Therefore, 1 BD$ is equivalent to 1.35 EC$.
