The normal price is gotten by find the 5% discounted price and adding it to the amount paid.
The normal price is £580
<h3>Prices and Discounts</h3>
Given Data
Discount = 5%
Amount paid = £551
Let the normal price be x
let us find 5% of x
= 5/100 *x
=0.05x
Hence the discounted amount is £0.05x
We know that the amount paid = Normal Price - Discount
Substituting our data
551 = x-0.05x
551 = 0.95x
Divide both sides by 0.95
x = 551/0.95
x = £580

Answer:
<h2>
a = 62°</h2>
Step-by-step explanation:
<h3>
a = 360° - (243° + 55°) = 360° - 298° = 62°</h3>
Arranging in ascending order we have
52 55 59 60 62 65 65 66
The median = (60+62)/2 = 61
The mean = 484 / 8 = 60.5
range = 66-52 = 14
interquartile range = 65 - 57 = 8
pairs = 65
