Answer:
a. £ 26.25 b. We would require less than 35 tiles depending on the width of the gap.
Step-by-step explanation:
a. To find the number of tiles needed, we divide the area of the room by the area of the each tile.
So, 350 cm × 210 cm ÷ (70 cm × 30 cm) = 5 × 7 = 35
So, we need 35 tiles.
Since each tile costs 75 p, it will cost 35 tiles × 75 p/tile to tile the wall = 2625 p = £ 26.25
b. If there had to be a gap between the tiles, we would require less than 35 tiles. The width of the gap would also determine the amount of tiles needed.
Answer:
x = 9.17 (nearest hundredth)
The variable x is the amount the student needs to save each month in addition to his usual saved amount of $20.
Step-by-step explanation:
350 = 12(x + 20)
Multiply out brackets: 350 = 12x + 240
Subtract 240 from both sides: 110 = 12x
Divide both sides by 12: 9 1/6 = x
x = 9.17 (nearest hundredth)
The variable x is the amount the student needs to save each month in addition to his usual saved amount of $20.
