Answer:
<h2>The required percentage is 65.45%.</h2>
Step-by-step explanation:
The total costing is 
35% were given to the charity, hence 350 were given to the charity.
There are (1000 - 350) = 650 lapel pins remaining.
60% of 650 = 
werre sold for 3.00 each. Hence, earning from here is 
.
40% of 650 = 260 were sold at 5.00 for 2. It can also be said that 
were sold at 5.00 each. Earning from this section is 
Total earning is (1170 + 650) = 1820.
Profit percentage =

Answer:
(x+16)²+(y-30)²=1156
Step-by-step explanation:
We have given:
center at (-16,30). It means h = -16 and k=30
and it passes through the origin (0,0)
Thus the radius will be distance between (-16,30) and (0,0)
r=√(-16 - 0)²+(30-0)²
r=√256+900
r²=(√1156)²
r²=1156
Now apply standard equation of circle:
(x-h)²+(y-k)² = r²
(x+16)²+(y-30)²=1156
Thus the equation is (x+16)²+(y-30)²=1156 ....
