Answer:
The cost to make one sandwich: S
Number of sandwiches the band sold: 73
The amount of money the band receives for making one sandwich: S+0.2S
The profit the band earns from selling one sandwich: 0.2S
Step-by-step explanation:
In the word problem, it says that it takes S dollars to make one sandwich.
In the word problem, it states that the band sells each sandwich for 20%(.2) more than it costs to make. This can be described as 0.2S
S+0.2S can describe how much profit the band makes.
73 represents how many sandwiches the band sold.
Answer:
It's just a simultaneous equation
Step-by-step explanation:
Let a big bag of sugar = x
Let a small bag of flour = y
x+x+y = 12kg
2x+y = 12kg ... 1
x-y = 2kg ... 2
Add 1 and 2
2x+y = 12
+
<u> </u><u> </u><u>x</u><u> </u><u>-</u><u>y</u><u> </u><u>=</u><u> </u><u> </u><u>2</u>
3x = 14
x = 14/3 = <u>4.66</u>
Substitute value of x into 1
2(4.66)+y = 12
9.333 + y = 12
12 - 9.333= 12
y = <u>2</u><u>.</u><u>6</u><u>6</u>
Hope you understand it
And I hope my answer was of help to you.
Its a
because you add 6x to the other side with the 42 which would look like 6x + 42
and divide by 2 on each side which equals
