An item that originally cost $100 is decreased by 8%. the reduced price is then increased by 8%. the resulting price is

The resulting price is $99.36.

Step-by-step explanation:

Original cost of the item = $100

The decrease percentage is 8% or 0.08

So, the reduced price becomes :

dollars

Now again the reduced price is increased by 8%.

So, multiplying the reduced price by 8% and adding it again we get;

=$99.36

So, the resulting price is $99.36.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
