Answer:
S=5000(1+(0.05)(8)).
Step-by-step explanation:
The loan is 5000, the rate is 5% and years are 8. So the amount is 7000. To find amount we use formula, S=P(1+ni). P is 5000 which is a loan. N is a number of years and i is the rate of interest. So by putting values in the formula, S=5000(1+(0.05)(8)).
Answer:
Step-by-step explanation:
The total cost for the month of October will be $64.5
Step-by-step explanation:
Given,
September charges = $51
Minutes used = 120 minutes
Cost per minutes = $0.30
Cost of 120 minutes = 120*0.30 = $36
Let,
Monthly fee = x
Monthly fee + 120 minutes charges = 51
x+36=51
Subtracting 36 from both sides
The company charges $15 monthly fee.
Minutes used in October = 165 minutes
Let,
y be the total cost for October.
Monthly fee + minutes*per minute charges = Total cost for October
x+165*0.30=y
The total cost for the month of October will be $64.5
