We have
Multiplying through by 1100,
Squaring (which means we need to check later),
Clearly there's no way that giant number would work; must be extraneous.
Answer: 3.94
Merry Christmas!
equation csn be represented as
money left = 500 - (n-1)×4.65
so we can see in first week money left
= 500 - (1-1)×4.65= 500-0=500
which is true because first week chaya got gift card and does not spend any money.
now lets assume that on week n money left is 327.95
so by equation
500 -(n-1)×4.65 = 327.95
500- 327.95 =( n-1)× 4.65
n -1 = 172.05/4.65=37
n = 37+1 = 38
in 38th week money left would be 327.95
I don’t know why I never think there’s that many people
sum of two angles of triangle are equal to the exterior angle of triangle
Neither...
205/1000 equals .205
So they are both the same.
Hope this helps -J
