Question

The money jordan is called the dinar.the exchange rate is $3 yo 2 dinars.find how many dollars you wuold recevie of you exchanged 22 dinars

Answer 1

You'd receive $33 for 22 dinars.

Proportionality:
a/b = c/d
where: cross products are equal  ad = bc

a = 3 ; b = 2 ; c = x ; d = 22

3/2 = x/22
3*22 = 2x
66 = 2x
x = 33

You would receive $33 dollars if you exchanged it to 22 dinars.
