Question

Latanya made a 17-minute phone call from her hotel in France and was charged 17 euro. At the time, $1 was worth 0.82 euro. Find the cost per minute of the call in dollars.

Answer 1

17 euro/17 minutes = 1 euro/minute
1 euro/minute * $1/0.82 euro

Answer 2

thats the answer

Answer 3

17? @mathstudent55

Answer 4

1/.82 = x/17 ($1 is to .82 euros = $x is to 17 euros) cross multiply
(.82)(x) = (1)(17)
.82x = 17
x = 17/.82
x = 20.73

now that is the price for 17 minutes. You want the price for a minute.
17/20.73 = 1/x (17 min to 20.73 = 1 min to $x) cross multiply
17x = 20.73
x = 20.73/17
x = 1.219 = 1.22

It would cost $ 1.22 per minute
