Sam is eating a Big Hamburger. The first bite was 20% of the Hamburger, the second bite was 20% of what is left and so every next bite is 20% of what is left.
a) How much did the Hamburger weigh originally, if after the second bite there was 160g of it left?

250g

Step-by-step explanation:

To calculate the original weight, you just have to find how much was left of the hamburger after the second bite.

Say that the hamburger is x grams.

0.64x = 160

x = 250

I feel sorta bad but, I got pretty much the same answer...

250g

Step-by-step explanation:

To calculate the original weight, you  have to find how much was left of the hamburger after the second bite.

Say that the hamburger is x grams.

0.64x = 160

x = 250

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0

$450 i think. hope this ☺
