Answer:

£374

Explanation:

Let d represent Carol's decreased wage, w represent its original value, and i represent that wage with an increase.

We want to find i = w(1 +10%) = 1.10w.

We have d = w(1 -10%) = 0.90w.

Solving the latter for w, we find ...

w = d/0.90

Substituting this into the expression for i, we get ...

i = 1.10(d/0.90) = d(1.10/0.90) = d(11/9)

Then the increased wage would have been ...

i = £306(11/9) = £374

Had Carol received a 10% increase, her weekly wage would be £374.
