First make and equation. Since you want to find the number of the day where both charge the same total amount, you would make the equation:

let x = the number of days

110+46 (x) = 70+54 (x)

Solve:

110-70+46 (x) = 70-70+54 (x)

40+46 (x) = 54 (x)

40+46 (x) - 46 (x) = 54 (x) - 46 (x)

40=8 (x)

40/8=8x/8

5=x

Therefore your answer would be 5 days
