About 25 animals were going towards the river
Answer:
Option $152.19
Step-by-step explanation:
Data provided in the question:
Previous balance = $152.35
Finance charge = $1.78
New purchases of $45.23 and $15.67
Payment = $50.00
Credit = $12.84
Now,
New Balance
= [Previous balance + Finance charge + New purchases ] - [ Payments + Credits ]
= [ $152.35 + $1.78 + ($45.23 + $15.67) ] - [$50.00 + $12.84 ]
= $215.03 - $62.84
= $152.19
Hence,
Option $152.19
Answer:
The car's average 18 number of miles per gallon
Step-by-step explanation:
The car has different efficiencies depending if its used on highway or city streets.
The efficiency on a highway is:
The efficiency for city driving is:
We now that the car uses twice as many gallons for city driving as for highway driving. This means that, for every gallon consumed, 2/3 are for city driving and 1/3 are for highway driving.
Then, we can calculate how many miles makes the car on average as:
We can use the compound interest formula
F=P(1+i)^n
where
F=Future value of investment to be found
P=present value of investment ($1000)
i=interest per period (1/4 year)=0.04/4=0.01
n=number of periods (3 years * 4 quarters = 12)
Substitute or "Plug in" values, so to speak,
F=1000*(1+0.01)^12
use a calculator to do the sum
=1126.83 (to the nearest cent, and use the proper rounding rules)
