Answer:
The interest when rate is 5.2% is $48.88
Step-by-step explanation:
if interest (I) varies directly as interest rate (R)
Then
I ∝ R
I=cR
c= constant
if interest is $47 when interest rate is 5%
47 =.05c
c = 940
if interest rate is 5.2% then
I = 940 x .052
=48.88
=$48.88
the answer would be 12 and 8
Answer: 50 holes
Step-by-step explanation: I find an easy way to answer questions like this is by 'dimensional analysis'....
Dimensions mins/holes and mins
mins / (mins/holes) = holes (because 'mins' cancel out)
25 mins / (6 mins/12 holes) = 300/6 holes = 50 holes
