first day --> x

2nd day --> x+7

etc

x + x+7 + x+14 + x+21 + x+28 = 125

5x = 55

x = 11

x = (x+7) + (x+14) + (x+21) + (x+28) =

125,

5x + 70 = 125,

5x = 125 - 70 = 55,

x = 11.

X + (X + 7) + (X + 14) + (X + 21) + (X + 28) = 125.

X + X + X + X + X = 5X.

7 + 14 + 21 + 28 = 70.

5X + 70 = 125

5X = 125 - 70 = 55

X = 11.

I'm glad i could help.
