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 = 
Yes you are correct! It doesn't have a solution which means no solution, hope this helps! :D
F(x) = 5(-3x) ^2 - (-3x) + 1
f(x) = -8x ^2 + 3x + 1
f(x) = -8x ^3 + 3x
Answer:
1. 15
2. 8
Step-by-step explanation:
The two sequence are geometric progression GP, because they follow a constant multiple (common ratio)
The nth term of a GP is;
Tn = ar^(n-1)
Where;
a = first term
r = common ratio
For the first sequence;
The common ratio r is
r = T3/T2 = 540/90 = 6
r = 6
T2 = ar^(2-1) = ar
T2 = 90 = ar
Substituting the values of r;
90 = a × 6
a = 90/6
a = 15
First term = 15
2. The sam method applies here.
Common ratio r = T3/T2 = 128/32 = 4
r = 4
T2 = ar^(2-1) = ar
T2 = 32 = ar
Substituting the values of r;
32 = a × 4
a = 32/4
a = 8
First term = 8
Did this a couple years ago, im kinda lost xD . sorry
