Answer:
Step-by-step explanation:
HI there!
From the question;
Principal (p) = 300
Annual rate (r) = 3%
Time (t) = 4 yrs
Now;
Interest (I) = 
I = 
I = 
Therefore the interest earned is 36.
Again;
New balance (A) = principal + interest
= 300+36
Therefore, the new balance is 336.
Hope it helps!
Answer:
X=22.5
Step-by-step explanation:
Y=kX
20=15k
k=4/3
For X when Y=30
30=4/3×X
Cross multiply
4X=90
X=22.5
95/100 = 0.95 <== if she missed 5 out of 95, then she got 95 out of 100
