Question 622114: I just need checking if I have answered this question correctly.
Mary and Ann together receive a total of £306.00 for babysitting. Ann is paid for 14 days work and Mary is paid for 15 days work. Ann's pay for 6 days work is £6 more than Mary gets for 4 days. Work out how much they each earn per day.
I worked out that over 14 days, Ann would get £20.00 more than Mary over the period. I then gave Mary's earnings as x. So 2x + £20 = £306. x = £143. Therefore, Mary earns £143 and Ann earns £163.
Thanks.
