Answer:
The cost of each pound of jelly beans: $2.75
The cost of each pound of almonds: $3.75
Step-by-step explanation:
A = The cost of each pound of almonds
J = The cost of each pound of jelly beans
9A + 7J = 53
3A + 5J = 25
Multiply 3A + 5J = 25 by (-3)
-9A -15J = -75
Now 2 new equations:
9A + 7J = 53
-9A -15J = -75
------------------------------Add
-8J = - 22
J = 2.75
3A + 5(2.75)= 25
3A + 13.75 = 25
3A = 11.25
A = 3.75
Answer:
h = 7, k = -1
Step-by-step explanation:
g(x) = f(x + 7)
g(x) = 2(x + 7) - 1
g(x) = 2(x + h) + k
h = 7, k = -1
0.15 * 20 = 3

Answer:Find the amount the store marked up the CDs by.
12.95 * .08 = 1.034 which rounds to 1.04
Add that to the former price.
12.95 + 1.04 = 13.99
Multiply by 4 to see how many 4 CDs cost.
13.99 * 4 = 55.96
Multiply by .1 to see how much the discount is.
55.96 * .1 = 5.596 which rounds to 5.60
Subtract the discount from the original price.
55.96 - 5.6 = 50.36
It costs $50.36 to buy four CDs this year.
