John has a jar filled with 150 coins made up of quarters and nickels. The total value of the coins is $26.70. 

Let x represent the number of quarters in the jar. Which equation can be used to find the number of quarters?

A. 
0.05x + 0.25(150 – x) = 26.70 

B. 
0.25x + 0.05(150 – x) = 26.70 

C. 
0.25x + 0.05(x – 150) = 26.70 

D. 
0.05x + 0.25(x – 150) = 26.70
