The Bank of France sells U. S. dollars ($) at a rate of ($1.40)/(€1) and buys U. S. dollars at a rate of ($1.80)/(€1). At the beginning of a trip, Sandra exchanged $420 to get €233.33. At the end of the trip, she is left with €36, so she exchanges the €36 back to U. S. dollars. How many U. S. dollars will Sandra receive in exchange?

the answer is c hope it

step-by-step explanation:

20%

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
