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?

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
