Question

Using the equation

e=17/20d, how many U.S. dollars (d) have the same value as 1 Euro (e)?

a. $1.20
b. $0.85
c. $1.00
d. $1.15

Answer 1

Using the equation e=17/20d and substituting e with 1, we find that d is approximately $1.176, which is closest to option (d) $1.15.

Step-by-step explanation:

To find the number of U.S. dollars (d) that have the same value as 1 Euro (e), we can use the given equation e=17/20d. We substitute e with 1 euro (since we want the equivalent of 1 euro) and solve for d.

1 = 17/20d

Dividing both sides of the equation by 17/20 to solve for d gives us:

d = 1 / (17/20)

d = 20/17

Now simplify to find the value of d:

d = $1.176 (rounded to three decimal places)

Looking at the provided options, the closest value to our calculation is option (d) $1.15.
