First, you have to calculate what one American dollar is worth in pesos. 3000 pesos = 270 American dollars, so 3000pesos/270american dollars = 11.1111.... so one American dollar is worth 11.1111... pesos. Calculating how much he has left in American dollars, 100pesos / 11.1111 (1 American dollar in pesos) = 9. He has 9 American dollars.
TIP: You would think it would equal 9.00000000000....1 but since the zeroes go on forever, the one never comes up, which makes it equal to 9.

Answer:
E) 166
Step-by-step explanation:
Standard deviation is 10
Margin error for the problem is 2
Probability 99%, that means thet the siginficance level α is 1 – p
α = 1 – 0.99 = 0.01
margin of error (ME) can be defined as follows
ME = Z(α/2) * standard deviation/ √n
Where n is the sample size
Z(0.01/2) = Z(0.005)
Using a z table Z = 2.576
Now, replacing in the equation and find n
2 = 2.576 * 10/ √n
2 = 25.76 /√n
√n = 25.76 /2
√n = 12.88
n = 12.88^2
n = 165.89 ≈166
Her profit is $ 13.25. It’s simple math all you have to do is subtract. 2.25 - 15.00= 13.25
