Answer:
Umm whats the question
Step-by-step explanation:
Hi there!
First we need to realise that the 18% discount equals John's savings. Therefore 18% of the original price is $13.23.
When we know 18% of the price, we can also find 1% of the total price.
18% = $13.23
Divide both sides by 18.
1% = $0.735
To find the total price, which equals 100%, we know only need to multiply both sides by 100.
100% = $73.50.
Therefore, the original price for the coat is $73.50.

Answer:
Hayden's hourly rate is $30
Extra hour rate is 1.5×30=$45
given that he earned $2175 by working 40 regular hours, the number of overtime hours he worked will be given as follows;
let the number of overtime be x
hence total amount earned will be:
(40×30)+(45×x)=2175
1200+45x=2175
45x=2175-1200
45x=975
solving for x we get
x=975/45
x=65/3=21 2/3 hours
Therefore the answer is c.562.50
Step-by-step explanation:
brainliest please
we know that
To find how long are 
sections placed end to end
Multiply the number of sections by the length of one section
so
therefore
<u>the answer is</u>
Let x = the length of the rectangle
Let w= the width
Two sections are required, hence 2w of fence required
2x+3w=500
this can be written as:
3w=1500-2x
w=(1500-2x)/3
Area=x*w
replacing w with our expression:
A=x(1500-2x)/3
A=(500x-2x^2)/3
This is a quadratic equation, if we find the axis of symmetry we will know what value of x gives maximum area:
Axis of symmetry: x=-b/2a
From our equation we get:
a=-2/3; b=1500/3
thus
x=(1500/3)/(-(-2/3))
x=750
thus the maximum area will be given by length of 750
