Answer:
x = 535 + 3/4n Over 8 --> Or in simplified form --> 66.875 + 3/32n
y = -166 / 3-4n
Step-by-step explanation:
1-) To find y, we will have to get rid of x in one of the equation.
So, we will multiply first equation by -4.
> -4 ( 2x + ny ) = -4 ( 51 )
> -8x - 4ny = -204
Then we will use the elimination method.
> -8x - 4ny = -204
8x + 3y = 38
+ -----------------------
> 3y - 4ny = -166
To isolate y, we will factor it out.
> y ( 3 - 4n ) = -166
Finally, we will divide ( 3 - 4n ) from both sides to achieve our desired result that the question asks.
> y = -166 / 3 - 4n
2-) To find x, we will substitute our y result into the second equation.
> 8x + 3 ( -166 / 3 - 4n ) = 38
> 8x - 498 + 1 - 3/4n = 38
> 8x - 497 - 3/4n = 38
> 8x - 3/4n = 535
> 8x = 535 + 3/4n
> x = 535 + 3/4n Over 8
> x = 535/8 + 3/32n
> x = 66.875 + 3/32n
It looks messy but I hope it will be understood.
If I have any inaccuracies please let me know.

Answer:
c = $5,400
Step-by-step explanation:
Given:
c = 0.9s
where,
s = amount sold
c = commission on sales
How much commission will he or she earn if the amount sold is $6,000?
Find c when she = $6,000
c = 0.9s
= 0.9 × 6,000
= 5,400
c = $5,400
(c, s) (5400, 6000)

<u>Situation 1: Recipe for tropical punch</u>
Number of cups of pineapple juice = 2.
Number of cups of orange juice = 3.
Total number of cub of juice = 2+3 = 5 cups.
Let us find % of pineapple and orange juice in total number of cups of juice.
% of pineapple = 2/5 = 0.40 = 40%.
% of orange juice = 3/5 = 0.60 = 60%.
<u>Situation 2: Jo's drink</u>
Number of cups of pineapple juice = 3.
Number of cups of orange juice = 4.
Total number of cub of juice = 3+4 = 7 cups.
Let us find % of pineapple and orange juice in total number of cups of juice.
% of pineapple = 3/7 = 0.429 = 42.9%.
% of orange juice = 4/7 = 0.0.571 = 57.1%.
Please note: <u><em>In Jo's drink pineapple juice % increased and orange juice % decreased by the tropical punch recipe.</em></u>
<h3>Therefore, Jo's drink will have a stronger pineapple taste.</h3>
