d how much does one fry cost
1 answer:
Answer:
The cost of one burger is $2.95
The cost of one fry is $1.45
Step-by-step explanation:
Let
x----> the cost of one burger
y---> the cost of one fry
we know that
----> equation A
----> equation B
Using a graphing tool
Remember that the solution of the system of equations is the intersection point both graphs
The intersection point is (2.95,1.45)
see the attached figure
therefore
The cost of one burger is $2.95
The cost of one fry is $1.45

You have the right idea and you are close to the correct answer. However that's not what your teacher is looking for in terms of steps.
The starting inequality is
She starts off selling 8 buckets. Then she sells b more to get a total of b+8
This total must be 20 or larger which is why I set b+8 greater than or equal to 20
Solve for b by subtracting 8 from both sides
So she needs to sell at least 12 more buckets to reach her goal
If you graphed this on a number line, then you would draw a closed circle at 12. Then shade to the right of the close circle.
