Aer Lingus has just purchased an Airbus A350 and expects to operate it for 15 years. Due to wear and tear, the aircraft's fuel efficiency is projected to decrease in a linear fashion over 15 years to be 73 % of its initial value. Due to gradually improving economic conditions, Aer Lingus expects the annual distance travelled by the aircraft to rise exponentially with an annual rate of increase of 1 %. Assuming all other factors remain constant, what will its annual fuel consumption be in 11 years as a percentage of its initial fuel consumption? Make sure you express your answer as a percentage but do not use the percent sign.
