Answer:

Step-by-step explanation:
Given


Required
Write an equation to determine the payment at a given week
At week 1, she'd have paid $8
At week 2, $16
Week 3, $24
..
.
This leads to arithmetic progression (AP):
8, 16, 24.....
To further solve, we'll make use of AP formula

In this case;



So, the equation becomes


Collect Like Terms


The above represents the amount paid at a particular week;
Amount owed, L is then calculated as follows;



2a - 1 < 6a + 7
bring all the a 's on one side and all the whole numbers on the other side.
2a - 6a < 7 + 1
-4a < 8
multiply everything by -1
4a > -8
a > -8/4
a > -2.
Hope you will understand.
Answer:
the last answer is what a unit rate is.
So what exactly is going on here?
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of packages of mix A nuts and let y represent the number of packages of mix B nuts
Since 8 ounces (oz.) of peanuts is used to produce a package of mix A and 6 ounces (oz.) of peanuts is used to produce a package of mix B. Also, No more than 120 oz. of peanuts can be used each day. This can be represented by the inequality:
8x + 6y ≤ 120 (1)
4 ounces (oz.) of cashew is used to produce a package of mix A and 6 ounces (oz.) of cashew is used to produce a package of mix B. Also, No more than 96 oz. of peanuts can be used each day. This can be represented by the inequality:
4x + 6y ≤ 96 (2)
The inequality from equation 1 and equation 2 is graphed using geogebra online graphing.
If x, y ≥ 0, the solution to the problem is:
(0, 0), (0, 16), (15,0), (6, 12)
