Answer:
19 bags of peanuts and 31 bags of pistachios were sold.
Step-by-step explanation:
This question is solved by a system of equations.
I am going to say that:
x is the number of bags of peanuts sold.
y is the number of bags of pistachios sold.
50 bags of peanuts and pistachios were sold
This means that
, that is: 
A grocery store recently sold a bag of peanuts for $0.76 and a bag of pistachios for $3.68. Were sold for a total of $128.52.
This means that:

Since 





19 bags of peanuts and 31 bags of pistachios were sold.
4(x – 3) + 4 < 10 + 6x
Distribute the 4 on the left side.
4x -12 +4 < 10 + 6x
Combine like terms on the left side.
4x-8<10 +6x
Subtract the 6x from both sides.
-2x -8<10
Add the 8.
-2x <18
Divide by -2 & flip the inequality symbol (it's a math rule which states that if you multiply or divide by a negative, you must flip the inequality symbol).
x> -9
That's your final answer.
okay so you would fill this in as
Y=(275x36)+800
this would then go to
y=10700-400
so the answer is 10300
hope this helps! enjoy!
