Answer:

x\y=5\3. ..........[I]

X=5y\3

X+y=56

X=56-y.........[ii]

substitute [I] &[ii]

5y\3=56-y

5y=3[56-y]

5y=168-3y

5y-3y=168

2y=168

y=168\2

y=84........[iii]

substitute [iii] in [ii]

X=56-84

X=-28

x-y=-28-84

=-112

Hello! I believe the answer to your question is C (hours). If t is the amount of time it takes, hours is a unit of time, therefore I assume that would be your answer. :)

Sidney took out payday loan for $1200 that charged $85 fee. If the loan matures in 2 weeks, what is approximate effective intere

pashok25 [27]

The amount owed increases by $85 in two weeks.

If the loan were "rolled over" at that point at the same interest rate, and this were done for a full year, the total amount owed would be 
(1285/1200)^26 * $1200 

If we subtract the original principle, $1200, and calculate the rest (the compounding interest) as a percentage of that principle, we get 

[(1285/1200)^26 * $1200 - $1200] / $1200 = 493%
