well its a simultaneous equations question 

q + n = 150

0.25q + 0.05n = 26.70

now solve them simultaneously

B.

anonymous · Answer

that doesn't make your point right dummy and I explain

anonymous · Answer

It's finals week and I just want some sleep. Thank you for giving me a quick answer Shay, and thank you for taking your time to explain @campbell_st

anonymous · Answer

@campbell_st explained it why repeat what he said all you're doing is substituting in the amount of nickles and quarters

anonymous · Answer

It's pretty obvious looking at the formula

anonymous · Answer

@campbell_st this is the ignorance I was referring to :/

anonymous · Answer

B is the answer, just plug in

anonymous · Answer

Shay was correct. You other guys take things way too seriously.

campbell_st · Answer

I can tell you how to solve the equation.... 

multiply the 2nd equation by -4 and then add the 2 equations...

this will eliminate the quarters (q) and allow you to find how many nickels you have 

so you get 

   q +      n =  150.00
  -q - 0.2n = -106.80
----------------------



so add the 2 equations and what do you get...?
