First multiply 57 x 30, then 30 x .35, then Ta da you have your answer (which is 598.5)
<u>Answer:</u>
0.45m + 33
<u>Step-by-step explanation:</u>
We are instructed to multiply the number the number of minutes Mr. Frotout spent on long distance calls by 0.45 the long distance rate then add 33 the flat monthly charge.
Assuming the number of long minutes spent on long distance calls by Mr. Frotout to be
, we can express the given situation as follows:

Answer:
14.44
Step-by-step explanation:
The formula says
A=p(1+r)^t
A 7800
P 3600
R 0.055
T ?
7800=3600(1+0.055)^t
7800/3600=(1.055)^t
Log(7800/3600)= t × log(1.055)
T=log(7800/3600)/log(1.055)
T= 14.44 years
10% of 70= 7
20%= 14
70-14=56
