Carrie is an american teaching english in mexico, and she currently has 45,000 pesos in her bank account. if the exchange rate changes from 1 u. s. dollar = 12.94 mexican pesos to 1 u. s. dollar = 13.09 mexican pesos, what happens to the value in u. s. dollars of the money in carrie's bank account?

Because of change in conversion rates, the value in Carrie's account decreases by $39.85.

Step-by-step explanation:

Total money in Carrie's bank account = 45000 pesos.

If exchange rate is 1 USD = 12.94 pesos, then in dollars the money in account is :

= $3477.588 ≈ $3477.59

If exchange rate is 1 USD = 13.09 pesos, then in dollars the money in account is :

= $3437.738 ≈ $3437.74

Now, if the conversion rate is 12.94 pesos then the amount in dollars is more, than when the conversion rate is 13.09 pesos.

The difference is dollars.

So, because of change in conversion rates, the value in Carrie's account decreases by $39.85.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
