Answer:
-75 m
Step-by-step explanation:
Use sea level as the reference point.
Initially the position is -50 m.
If the submarine goes up 15 m, then its new position is (-50 + 15) m, or -35 m.
If the sub now descends 40 m, its new position is (-35 - 40) m, or -75 m

Answer:
* Lucy spent £289.2 on tiles *
Step-by-step explanation:
We know that the tiles are present in a 13 to 2 ratio ( 13 : 2 ) so if there are 16 blue tiles that she buys, the number of red tiles bought should be represented the following -
= 
... now this is only assuming that the 13 : 2 ratio is meant by white : blue tiles. Let's solve through cross - multiplication,
13 
16 = 2
,
208 = 2,
= 104 white tiles
So if there are 104 white tiles, and 16 blue tiles, we can determine the total amount Lucy spent on tiles by associating the cost to the type of tile,
£2.80 16 = £44.8,
£2.35 104 = £244.4,
Total Amount Lucy Spent on Tiles = £44.8 + £244.4 = £289.2
