Correct answer is:
Step-by-step explanation:
Given that Number of bracelets with yellow beads is represented by 
Each bracelet with yellow beads is sold for $5.
Total money raised by bracelets with yellow beads = Number of bracelets sold 
Money raised by sale of one such bracelet = 
Also Given that Number of bracelets with Orange beads is represented by 
Each bracelet with orange beads is sold for $6.
Total money raised by bracelets with orange beads = Number of bracelets sold Money raised by sale of one such bracelet = 
Given that total money raised by sale of both type of bracelets is $660.
so, the first equation becomes:
It is also given that "<em>The number of bracelets with yellow beads that Sierra sold is 8 more than twice the number of bracelets with orange beads</em>"
So, by equation (1) and (2), the system of equations is:
Brad's profit was 30%
Further explanation:
Profit is the money someone earns on selling a product on more than its actual cost.
The formula for profit is:
Given
Purchase price of energy drinks = £9.25
Selling price of one bottle=£1
Selling price of 12 bottles=1*12=£12
Profit= Selling Price - Purchse price
=12-9.25
=£2.75
Brad's profit was £2.75
Now,
Profit percentage= (Profit/Purchase Price)*100
=(2.75/9.25)*100
=0.30*100
=30%
Brad's profit was 30%

Let's say the first number is -a, so "a" will be some positive value, and we multiply -1 to it, we get the -a
a consecutive number from it, is either, ahead or before it, so, -a + 1 or -a -1, is a consecutive integer, hmm let's use -a + 1 then
so, the two numbers are -a and -a + 1
we know their product is 600
we use the positive one, because we're using -1 in front of the "a"
what's the lesser integer? well, what's -a+1? which one is lesser?
