Ok so
t=time in seconds
therefor the smount lost for t seconds is 0.3 ties t or 0.3t
loss so it is ngative
-0.3t
the question is
243.5-0.3t=40% of 243.5
first, find 40% of 243.5
percent means partst out of 100 so
40%=40/100=0.4
'of' means multiply
40% of 243.5=0.4 ties 243.5=97.4
now the question is
243.5-0.3t=97.4
for ease, multiply whole equation by 10 to make no decimals
2435-3t=974
subtract 2435 from b oth sides
-3t=-1461
divide both sides by -3
t=487
answer is 487 seconds (aka 8 mins, 7 secons)
answer is 487 sseconds
As you can seen it moves by multiplied with -3
then next three terms are -648,1944,-5832 (B)
