To find the amount he will receive when he exchanges the pesos for dollars, you can use a rule of three using the information provided:
1 American Dollar is 3000/270 = 300/27 = 100/9 pesos.
270 dollars → 3,000 Mexican pesos
x ← 100 Mexican pesos
x=(270*100)/3,000=9 dollars
According to this, the answer is that he will receive 9 dollars.
