An item on sale cost 35%of the original price. The original price was $25. What was the sale price?

➩ $33.75

Original price of the item is $25

As it told that it costs 35% of the original price

Therefore

➡ $25 + (35% of 25)

➡ $25 + 8.75

➡ $33.75 ans.

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)
