Answer:

Read below

1. 270

2. 277

Step-by-step explanation:

I'm not too sure which answer you're looking for but I'll try to answer all of them :).

First of all, we can consider them in percentage form first.

If the first sale price is marked down by 30%, it is now 70%.

For the second, the price is marked down by 20% first, so 80%.

And then another 10% on top of the 80%. 10% of 80 is 8, so the second one is marked down 80-8, or 72%.

As we can clearly see, 72% is greater than 70% so the first deal( 30% off ) would give you a cheaper price

Now we move on to the actual prices.

First one is 70% of the original price, 70% of $385 is $269.5.

Second one is 72% of original price, 72% of $385 is $277.2

Don't forget to round to the nearest dollar!

1. 270

2. 277

Hopefully this helps! If I did it wrong feel free to tell me ;-;

Also lol relatable my works due tmr and i dont feel like doing it either ://

Mr. Black bought 2 magazines for $9.95 each and 1 book for $14.95. If the sales tax is 6%, what is the total cost of Mr. Black's
miss Akunina [59]

Answer:

$36.94

Step-by-step explanation:

Okay, so. This is what we do. There is two magazines and they cost 9.95 each multiply 9.95 times 2

9.95 x 2 = 19.90

Okay, then he buys a book for 14.95 we add 19.9. and 14.95

19.90 + 14.95 = 34.85

Then we have a sales tax of 6% we would multiply 34.85 time 6%

34.85 x 6% = 2.09

Then we would add. 34.85 + 2.09

34.85 + 2.09 = 36.94

Therefore your answer is $36.94

Hope this helps!!!

Rotation 90 degrees counterclockwise about the origin​
nataly862011 [7]

Answer:

  • Point W = (-3, 3)
  • Point X = (-3, 2)
  • Point V = (-2, 3)

<em>The rotation rule states that rotation 90° counterclockwise means (x, y) = (-y, x)</em>

<u>The new points would be equal to:</u>

  • Point W' = (-3, -3)
  • Point X' = (-2, -3)
  • Point V' = (-3, -2)

Try graphing it to see if the new points make sense<em>(because I'm not too sure :\)</em>

I need help with this math problem! Thanks!<br><br> -8 = -( x +4)
Damm [24]

Answer:

x = 4

Step-by-step explanation:

If the lonely negative sign infront of the brackets is confusing, it can be rewritten as -1.

To solve, simplify by expanding then isolate x.

-8 = -( x +4)

-8 = -1 ( x +4)       Distribute over brackets by changing the each term's sign

-8 = -x - 4            Start isolating x by moving everything to the other side

-8 +4  = -x -4 + 4        Add 4 to both sides so it cancels out on the right

-4  = -x

-4  = -1x           <= -x is the same at -1x

-4/-1  = -x/-1     <=divide both sides by negative 1

4 = x

x = 4      <= usually we write the variable on the left side

On one day a rickshaw puller earned 80.out of his earning he spent 68÷5 on tea and snacks,51÷2 on food and 22÷5 on repair of the
Alexeev081 [22]
Answer: $56.50
==================================
(instead of dividing each of them individually and them subtracting them one by one, combine them together as a fraction first and then subtract)

80 - (68/5 + 51/2 + 22/5)
= 80 - (136/10 + 255/10 + 44/10)
= 80 - (435/10)
= 80 - 43.5
= 56.5

He saved $56.50 on that
