Answer:
At x= 20.10723974, both f(x)=g(x)
Step-by-step explanation:
f(x) = 300(1-0.04)^x = 300(0.96)^x
g(x) = 60(1+0.04)^x = 60(1.04)^x
now equate both of them and calculate x
300(0.96)^x = 60(1.04)^x
5(0.96)^x = (1.04)^x
ln(5) + x ln(0.96) = x ln(1.04)
x={ln(5)}/{ln(1.04)-ln(0.96)}
x= 20.10723974
Answer:
xy < 60
Where x is the amount of subscription per month and y is the number of months
Step-by-step explanation:
Given Anna wants to spend less than $60 for the subscription
Let the amount of subscription per month be x
Let the number of months which Anna can enjoy her music be y
The total amount of money spent by Anna on subscription = ( The amount of subscription per month )( Number of months )
Total amount = xy
Given total amount < 60
So xy < 60
Therefore the above is the inequality recquired.
