So in 5 weeks, Marcie will have collected 25 stickers, and given away 15. She will have 10 stickers left. I hope that this helps! :)
To sum up, we only have the length of one side.
We need to find the width of the same side. -
20.5 x 20.5 = 420.25
To get the surface area, we multiply by six.
<u>Why?</u> There are six sides on a cube.
420.25 x 6 = 2521.5
Answer: 2521.5 cm
A) 95.8 % of £36 will be the new price
B) The answer to part A as a decimal is £34.488
C) The new price is £34.488
<h3><u>Solution:</u></h3>
Given that the price of a pedicure decreases by 4.2% from £36 on promotion
<em><u>A) What percentage of £36 will the new price be ?</u></em>
Given that £36 is decreased by 4.2 %
New price = 36 – 4.2% of 36

Now we have to find what percentage of £36 will the new price be
x % of 36 = 34.488

<em><u>B) Write your answer to part a as a decimal.</u></em>
Now, we have to find the new price in decimal form.

<em><u>C) Work out the new price.</u></em>
As we calculated, the new price is £34.488
