ANSWER:
Reserve rate = 1.03%
Step by step explanation:
Initial amount = $6000
Total sum = $2,00,000
A G.P(geometric progresssion) series is formed with initial value = 6000
Since the depositing cycle continues infinitely, therefore the sum of G.P formula will be taken for infinite values
S= a\1-r
where s= 2,00,000 (sum)
a=6000 (initial amount)
r= ratio (reserve rate)
2,00,000= 6000\1-r
r = 1.03 %
Answer:
True
Step-by-step explanation:
(20)(35) + (15)(15) - 125
This is right because the store bought 20 keyboards and sold each one for 35 dollars, and bought 15 phone chargers and sold each one for 15 dollars. so, 20 x 35 = 700 and 15 x 15 = 225. We use - 125 because we used that money to buy the products, so we need to subtract that out of the profit we are going to get. 700 - 225 = 925. Now we subtract the money we used, 925 - 125 = 800. The profit they gained was 800 dollars!
Answer:
R(x) = 1,969,110 +0.59x . . . . in dollars
Step-by-step explanation:
The basic revenue to the city from the 561,000 customers will be ...
561,000 × $3.51 = $1,969,110
The usage fee is still $0.59 per 1000 gallons, so the total for a total of x thousand gallons will be ...
R(x) = $1,969,110 + $0.59x
