answer

£2

explanation

12÷50%=6

12÷33%=4

6+4=10

12-10=2

2.04 pounds left.

Step-by-step explanation:

Whitney has 12 pounds pocket money

She spends 50% of it on magazines

50% of 12 pounds is 50/100 * 12 = 600/100 =         6 pounds

33% of 12 pounds is 33/100 * 12 = 395/100             3.96 pounds

Total Spent                                                                9.96 pounds

Amount left = 12 - 9.96 = 2.04

She has 2.04 pounds left.

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)
