A bucket holds 243.5 oz of water. The bucket loses 0.3 oz of water per second. In how many seconds will the bucket be 40% full

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
