In one quarter Stuart uses 2512 units of electricity. Part of his electricity bill is shown below. Units used = 2512 Cost of first x units at 12.86p per unit = £ Cost of remaining units at 11.8p per unit = £ Total cost of electricity used = £298 work out the number of units, at 12.86p per unit, that Stuart used. Give your answer to the nearest unit.
