How many packets did they buy in all?

thereisnousername · Answer

a = vanilla
b = chocolate

a + b = 27 packets
4a + 1b = $45

so now you have a simultaneous equation, can you solve from here?

pumpkin1102 · Answer

change the positive B to negative so that equation would become a = 27 - b so that would be 4a + (27 - b)  = 45 am I right so far? @ThereisnoUsername
