Question

Billy invests £800 for 5 years in a savings account.

Answer 1

Answer:

2 2/5 % or 2.4%

Step-by-step explanation:

Rate R = 100 x I /P x T

Where

I = interest £96

P = principal £800

T = time 5 yrs

Therefore

R = 100 x 96 /800 x 5

Multiply through

= 9600/4000

Cancel out zeros, we’re left with

= 96/40

Divide both the numerator and denominator by 4

= 24/10

Divide both the numerator and denominator by 2

= 12/5

= 2 2/5 % or 2.4%
