An odd function is symmetrical about the origin: g(-x) = -g(x).
The 4th selection is appropriate.
An equivalent expression could be 2.75, 100%+175%, or 300%-25%<span />
Regular price is
4 times 390=1560
tax=8.25%
1560 times 0.0825=128.7
add that
1560+128.7=1688.7 is price if didn't use promotion
if deal then
3 normall trees+1 that is 80% off
find the 4th tree
390 times 0.80=312 off
390-312=78
3 normal trees+78=3 times 390+78=1248
find the tax
0.0825 times 1248=102.96
add
1248+102.96=1350.96
compare prices
1688.7 no promotion
1350.96 with promotion
subtract
1688.7-1350.96=337.74
she saved $337.74
