After two weeks the duck will be .89 kilograms.
Starting price is 2.65, increased by .56
2.65+.56=3.21
Price is 3.21, decreased by .23
3.21-.23=2.98
Price is 2.98, increased by 1.02
2.98+1.02= 4
Price is 4, decreased by .48
4-.48=3.52
Now find the difference from the starting price (January) from the end price (May)
3.52-2.65=.87
<u>The difference from gas prices is $.87</u>
