The cost of meal = $30

The tip to the waiter = 8%%

Discount = 10%%

Cost = 30 + 0.08 * 30 - 0.1 * 30

Cost = 30(1 + 0.08 - 0.1)

Cost = $$29.40

A shop has a sale that offers 20% off all price. On the final day they reduce all the sale prices by 25%. Linz buys a radio on t
erastova [34]
Hmmmm is not very clear if the 25% is just 25% of the original price, or of the reduced price, but let's assume is of the reduced price.

say the original price is "x", 20% off that, means the sale price is 80% of the original price, or (80/100) * x, or 0.8x.

then Linz shows up on the last day, and she's got 25% off from that price plus a beanie baby and a free garden hose.

so if the price is reduced by 25%, then the sale price is just 75% of whatever it was, but it was already reduced to 0.8x, what is 75% of 0.8x?

(75/100) * 0.8x, or 0.75 * 0.8x, which is 0.6x, now 0.6 * 100 is 60 to change it to percentage format, or 60% overall percentage reduction from the original price.

Solve for x <br> (19x-18) <br> (7x+1) <br> (10x-9)
ExtremeBDS [4]

Answer:

Step-by-step explanation:

Exterior angle property: Exterior angles equals the sum of remote angles

19x - 18 = 7x + 1 + 10x - 9

19x - 18 = <u>7x + 10x</u> + <u>1 - 9 </u>    {Combine like terms}

19x - 18 = 17x - 8          {Subtract 17x from both sides}

19x - 17x - 18 = -8

        2x - 18 = -8         {Add 18 to both sides}

              2x = -8 + 18

             2x = 10

              x = 10/2

x = 5

Help me please i don't understand ​
lubasha [3.4K]

Answer:

See below.

Step-by-step explanation:

Variables:

L = length

W = width

P = perimeter

Equations:

L = W + 13

P = 2(L + W)

P = 2(W + 13 + W)

2(W + 13 + W) = 226

2(2W + 13) = 226

2W + 13 = 113

2W = 100

W = 50

L = W + 13 = 50 + 13 = 63

The length is 63 cm, and the width is 50 cm.
