Step-by-step explanation:
Let x be the price of an apple and y be the price of an orange.
We have been given that a fruit stand need $10 for 4 apples and 4 oranges. We can represent this information as:

We are also told that they need $15 for 6 apples and 6 oranges. We can represent this information as:
Therefore, our desired system of equations will be:

September
30-10=20 days
October 31
November 10
Time=20+31+10=61 days
A=42,000×(1+0.035÷365)^(61)
A=42,246.38
Interest earned
I=42,246.38−42,000
I=246.38
6y^2-7y-3-2y^2+9y+7 (pretend that you're multiplying -1 to 2y^2-9y-7 which is why 9y and 7 are positive now).
Now you're able to simplify your problem, so...
6y^2-2y^2= 4y^2
-7y+9y= 2y
-3+7=4
4y^2+2y+4
Might want to check my math but that's how you do it.
