Answer:
PE = 83 and Science = 71
Step-by-step explanation:
let P represent PE and S represent Science with P > S, then
P + S = 154 → (1)
P - S = 12 → (2)
Adding the 2 equations term by term eliminates S
2P = 166 ( divide both sides by 2 )
P = 83
Substitute P = 83 into (1)
83 + S = 154 ( subtract 83 from both sides )
S = 71
Hence PE mark = 83 and Science mark = 71
When put in a calculator, the answer is 12.22 (recurring)
Answer:
If you're asking for the interest:
a) 960
b) 80
c)2.63 approx.
Step-by-step explanation:
interest = principal x rate x time OR 
TIME IS IN YEARS.
Thus, the first would be 
% = 960
Second: 4 months = 
year
I = 4000xx6% = 80
Third: t = 4 days =
year
I = 4000x6%x ≈ 2.63
