Answer:
Yes, it is possible if the sweaters on sale are $7.40 each.
Step-by-step explanation:
The sweaters each cost $37. To purchase all four (for herself and 3 sisters) without a sale would be 4(37)= $148.
40% off the regular price would be 0.40(148)= $59.20 savings. She would spend 148-59.2= $88.80.
Is it possible to buy two regular price sweaters and two on sale for $88.80?
2(37)=$74. If we subtract from the sales total, 88.80-74=14.80. This means the two sweaters on sale must each be $7.40. It is possible to save 40%.

Answer:

Step-by-step explanation:
The point of intersection is found by equating the expressions for P:
6d = 5d +15
d = 15
p = 6d = 6·15 = 90
The point of intersection of the graphs is (15, 90).
The first equation graphs as a line with slope 6 through the origin.
The second equation graphs as a line with slope 5 through point (0, 15).
It is inconvenient to graph p and d using the same scale, so the attache graph has the vertical scale compressed somewhat.
Remark
Let the amount invest = x
(1/3 x) * 5/100 + (1/2 x) * 5.5/100 = 735 Multiply numerators and denominators together on each side of the plus sign.
5x/300 + 5.5x / 200 = 735
Multiply both sides of the equation by 600 to get rid of the denominators.
(5x/300)*600 + (5.5x/200)*600 = 735 * 600
(5x * 2) + 5.5x * 3 = 441000
10x + 16.5x = 441000 Combine the like terms on the left.
26.5 * x = 441000 Divide by 26.5 on both sides.
x = 441000/26.5
x = 16641.51 = invested amount <<<<< answer
Check
1/3 * 5/100 * 16641.51 = 277.36
1/2 * 5.5/100*16641.51 = 457.63
The total = 735 which is what it should be.
Answer: 2/x+4x^2
Step-by-step explanation:
Do distrubitive property.
SO mutiply 2/5 to 5/x which is 10/5x or 2/x
then 2/5 times 10x^2
10*2/5=20/5 or 4
Done.
Have a nice day! :)
