Question

1. Lucy is tiling her bathroom. She buys white and blue tiles in
the ratio of 13:2. Blue tiles cost $2.80 whilst white tiles
cost €2.35. If she buys 16blue tiles, how much does Lucy
spend on tiles in total?

Answer 1

Answer:

43.865 dollars.

Step-by-step explanation:

total parts = 13 + 2 = 15tiles

blue tile part in total tiles is 13/15 th part whereas white tails has 2/15 th part.

The total tiles Lucy brought = 16

so, the blue tiles in total are (13/15)×16 = 13.87 tiles and the white tiles in total are (2/15)×16 = 2.14 tiles.

Total cost for blue and white tiles are 13.87 × 2.80 = 38.836 dollars and 2.14 × 2.35 = 5.029 dollars respectively.

So Lucy spend 38.836 + 5.029 = 43.865 dollars in total
