50% of Brady's Halloween candy has been eaten. He has 68 pieces left. How much did he have
2 answers:
Answer:
136
Step-by-step explanation:
Brady has eaten 50% of the original amount. The final amount is 68. So think, what 50% of a number is equal to 68?
Let x= original amount
Let n= final amount
n=68
50%= 0.5
0.5(x)= n
Divide both sides by 0.5
x= n/0.5, we know n=68, sub in 68 for n
x= 68/0.5
x= 136
Therefore, Brady had 136 pieces originally.
136 pieces? Because 68 is half of it (50%) and 68 times 2 is 136
