Answer:

£210

Step-by-step explanation:

A decrease of 30% represents 70% of the original cost.

100% represents the original cost

Divide the price by 70 to find 1% then multiply by 100 for original cost

original cost = \frac{147}{70} × 100 = 2.1 × 100 = £210

Krystal’s poster project for reading class is 2 feet high and 1 1 2 feet wide. Her friend Victoria’s poster is 4 feet high and 1
Bess [88]

The area of Victoria's poster is twice the area of Krystal's poster.

<h3>How compare the areas of two similar posters</h3>

The two areas are shown in the image attached below. Each poster represents a rectangle and the ratio between the two areas (r_{A}), no unit, is defined by the following formula:

r_{A} = \frac{w_{V}\cdot h_{V}}{w_{K}\cdot h_{K}}     (1)

Where:

  • w_{V} - Width of Victoria's poster, in feet.
  • h_{V} - Height of Victoria's poster, in feet.
  • w_{K} - Width of Krystal's poster, in feet.
  • h_{K} - Height of Krystal's poster, in feet.

If we know that h_{V} = 4\,ft, w_{V} = 1.5\,ft, h_{K} = 2\,ft and w_{K} = 1.5\,ft, then the ratio between the two areas is:

r_{A} = \frac{(4)\cdot (1.5)}{(2)\cdot (1.5)}

r_{A} = 2

The area of Victoria's poster is twice the area of Krystal's poster. \blacksquare
