Answer:
£18
Step-by-step explanation:
Let
x = original price of the game
Increase in price = 1/2
New price = £27
x + 1/2x = £27
2x+x/2 = 27
3/2x = 27
x = 27 ÷ 3/2
= 27 × 2/3
= 54 / 3
x = £18
Therefore, the original price of the game is £18

I saw the image that should accompany the above problem.
Courtyard: Length=22 ft; Width = 12 ft
Fountain: Length = 6 ft; Width = ?
Area of the courtyard = 22 ft * 12 ft = 264 square feet
Part of the courtyard covered with stone has an area of 246 square feet.
Area of the fountain = 264 square feet - 246 feet = 18 square feet.
A) Width of the fountain.
Area of the fountain = Length * width
18 square feet = 6 ft * w
18 sq.ft / 6ft = w
3 ft = width
B.) Fraction of the area of the courtyard will be occupied by the fountain.
Area of the fountain: 18 square feet
Area of the courtyard: 264 square feet
18/264 = 3/44
18 ÷ 6 = 3
264 ÷ 6 = 44
Answer: 194
