Answer :
Well. The percentage increase would be 30%.
Its would have to be rounded. If you time .80 by the decimal of 30 percent, which is .30 you will receive .24, that will equal out to 1.04.
.80 x .30= .24
.80 + .24 = $1.04
so assume .8=100%
1.05-0.8=iincrease=0.25
find what .25/.8=
.25/.8=2.5/8=(use calculator)=0.3125
percent means parts out of 100
so
0.3125/1 times 10/10=3.125/10 times 10/10=31.25/100
the percentage increase was 31.25%
1.05-0.8=iincrease=0.25
find what .25/.8=
.25/.8=2.5/8=(use calculator)=0.3125
percent means parts out of 100
so
0.3125/1 times 10/10=3.125/10 times 10/10=31.25/100
the percentage increase was 31.25%
