Janet bought a $15 candle that had a discount of 60%. What was the cost after the discount?

6 dollars

Step-by-step explanation:

Since we are trying to find out the cost after subtracting the discount from the original cost we are going to have to convert 60% into a decimal.

60%/100 = 0.6

We then multiply 0.6 by 15 to get how much 60% is to 15:

0.6 * 15 = 9

We then subtract 9 from 15 to get what money you still have to pay for the discounted candle:

15 - 9 = 6

So Jane will have to pay $6 for the candle

i dont know it

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)
