Monica deposits $200 into a savings account that pays a simple interest rate of 3.3%. Paul deposits $300 into a savings account that pays a simple interest rate of 2.3%.

50% of Brady's Halloween candy has been eaten. He has 68 pieces left. How much did he have

Answers

136 pieces? Because 68 is half of it (50%) and 68 times 2 is 136

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.
