To solve this problem we can use simple proportion If 270 − − − − − − − − − − − − − − − − − − − − − − − − − 3000 p esos x ---------------------------100 pesos (x m e an s t ha tw e d o n t kn o w h o w m u c h ) N o ww ecross m u lt i pl y in g t o g e tp ro p or t i o n x ∗ 3000 = 270 ∗ 100 N o ww e j u s tt oso l v ee q 3000 x = 27000 / : 3000 x = 27000 : 3000 x = 9 - its the result
You will receive 9 dollars when you exchange the remaining 100 pesos. This is calculated by setting up a proportion based on the initial exchange rate. By cross-multiplying and solving, we find that 100 pesos is equivalent to 9 dollars.
