Sally has $4.60 change in her pocket. she has only 20 cents and 50 cent coins, 14 coins in total. If t is the number of 20c coins that sally has, find t.
the answer is 6 T=6
Here is HOW to solve it:
t = 20 cent coins value = 20 t
14-t = 50 cent coins value = 50 ( 14-t) Totalled, these = 460
20 t + 50 ( 14-t) = 460
-30t = -240
t = 8
