Galina-37 [17]

Answer:

The value of Lucys house  at the start of 2017 is 231525.

Step-by-step explanation:

It is given that the initial value of Lucys house is 200,000. The  at the start of 2017.

The exponential function is defined as

P=P_0(1+r)^t

Where, P₀ is initial value, r is growth rate, t is time in years.

The value of house is defined by the function

P=200000(1+0.05)^t

Where, t is number of years after 2014.

P=200000(1.05)^t

The difference between 2017 and 2014 is 3 years.

P=200000(1.05)^3=231525

Therefore the value of Lucys house  at the start of 2017 is 231525.

Amina posts three large letters the postage is the same for each letter she pays with a £20 note her change is £14.96 what is th
soldi70 [24.7K]

Answer:

The cost of posting one letter = £1.68

Step-by-step explanation:

Total amount Amina has = £20

Amina's change = £14.96

Total cost spent on posting the letters = £20 - £14.96 = £5.04

And we're told that she posts 3 letters in total, with the cost of posting each letter the same.

Cost of posting 3 letters = £5.04

Cost of posting only 1 letter = (£5.04/3) = £1.68

Hence, the cost of posting a letter = £1.68

Hope this Helps!!!
