Bethany says, Using these exchange rates, £1 is worth 1.17 euros.
<u>Step-by-step explanation</u>
1 euro = 1.07 dollars
£1 = 1.25 dollars
Now ,
⇒ £1 = 1.25 dollars
⇒ £1 =
⇒ £1 =
⇒ £1 =
⇒ £1 =
⇒ £1 =1.17 euros
Therefore , Bethany says, Using these exchange rates, £1 is worth 1.17 euros.
Answer:
The common difference (or common ratio) = 0.75
Step-by-step explanation:
i) let the first term be = 80
ii) let the second term be =
. r = 80 × r = 60 ∴ r =
= 0.75
iii) let the third term be =
. r = 60 × r = 45 ∴ r =
= 0.75
iv) let the fourth term be =
. r = 45 × r = 33.75 ∴ r =
= 0.75
Therefore we can see that the series of numbers are part of a geometric progression and the first term is 80 and the common ratio = 0.75.
