Answer:
Answer:£23.85 is your answer.
x+2.5%ofx=£977.85
x(1+2.5/100)=£977.85
x=£977.85/(1.025)=954
saving money will be =£977.85-954=£23.85
Answer:
Increase
Step-by-step explanation:
The researcher records the following estimates: 450, 426, 310, 500, and 220.
The mean of these estimates is derived below.
Mean = (450+426+310+500+220)/5
=1906/5=381.2
If the researcher removes the estimate of 220.
The mean of the other numbers will be:
Mean =(450+426+310+500)/4
=1686/4=421.5
By comparison of the two mean, we can see that the value of the mean will increase.
