By any chance will it be (1,1)
Answer:
$2.64
Step-by-step explanation:
Selling them at 5 cents each ($0.05), he could sell 1 dozen buttons for
12 * $0.05 = $0.60
As he bought them at $0.38 per dozen, the profit per dozen would be
$0.60 - $0.38 = $0.22
As 12 dozen is 1 gross, the profit per gross would be
12 * $0.22 = $2.64
Basically what you need to do is:
3000 X 0.04^3
I would give an answer but I don’t have a calculator at the moment, but I hope this helps
Remark
The trick here is to realize that you have to find the number both have in order to find the difference. That means you take (effectively) 3/8 and 5/8 to find out how much each of them has. The 8 stands for the 136
Step One
Find the number of stamps Alex has. Remember his ratio is the smaller so he will have 3/8
Alex = 3/8 * 136
Alex = 408/8 = 51
Step 2
Find the number that Freddy has.
The total is 136
<u>Formula</u>
Freddy = Total - Alex
Freddy = 136 - 51
Freddy = 85
<u>Check</u>
Let us see if 5/8 * 136 = 85
5*136/8 = 680 / 8 = 85 So your answers are correct.
Difference
Difference = 85 - 51 = 34 which is how many more stamps Freddy has than Alex.
Answer:
)
Step-by-step explanation:
This system we can solve by substitution method :
y=13x-1
y=9x+4
_______
y=13x-1
13x-1=9x+4 (instead y in second equation we use 13x-1 and first rewrite)
_______
y=13x-1
13x-9x=4+1 (subtract 9x and add 1 for each side)
______
y=13x-1
4x=5 (divide by 4)
_____
y=13x-1
(instead x in first eq we write 5/4)
______
