Answer:
Purchase amount = $642
Step-by-step explanation:
Given that:
Jeff has bought:
cell phone = $500
4 Accessories = 4 * $25
4 acessories = $100
Total = $500 + $100 = $600
As the sale tax is 7% so
Sale tax = 7% (600)
Sale Tax = 0.07(600)
Sale Tax = $42
So the purchase amount will be Total + Sale Tax
Purchase amount = $600 + $42 = $642

For this case we have the following equation:
c + b = 55
Where,
c: number of CDs
b: number of books
For c = 30 we have:
30 + b = 55
From here, we clear the value of b.
We have then:
b = 55-30
b = 25
Note: observe in the graph that when the value of c is 30, the value of b is 25.
Answer:
the amount Alison may spend on books in March if she spends 30 on CDs is:

See attached image.
4a² − 20a + 25. is the answer.
Answer:
3432 different ways.
Step-by-step explanation:
Since the men and women are not individually characterized (no names are given) we will treat them as similar objects with regards to permutations.
Let's leave out the two women that receive the award first.
We now have 7 men and 7 women to receive the reward.
This translates to the following permutation:
= 3432 different ways to give out the awards.
The 7! in the denominator exist to account for same objects, 7! for men and 7! for women.
