Answer to Question #19727 in Abstract Algebra for dollydawson




 Find the missing value. the principal is $500, the time is 7 years, the simple interest is $140.00, i have to find the rate.
The simple interest formula is:  
I = P*R*T, where   
I - interest, P - principal, R - rate, T - time in years of the loan.  
Then, R = I/(P*T) =140/(500*7) = 0.04  
The rate is 4%
a sum of money becomes 3 times in 5 years at simple interest. in how many years will the same sum become 6 times at the same rate of simple interest? what’s your day rate. answer: `1.00` hi @sam\_cat - there was another topic on this query. i can't find it, so i've tweaked yours to make it more searchable moving forwards. 

this is to do with the direct debit figure. we look at your prices for the two year plan, and the annual consumption of the property, getting an annual spend and a monthly cost (if you divide that figure by 12). the tariff that you're on now just displays your current direct debit, which will of course take into account your current credit balance. 

tim the discover it chrome's intro offer for balance transfers is 0% apr for 14 months.
for any balance transfer posted to your account until april 10, 2021 you get a promotional apr of 0% for 14 months from first date of transfer.
after the intro apr period expires, your regular transfer apr could be 11.99% - 22.99% variable.
keep in mind, though, that this card has a 3% intro balance transfer fee, up to 5% fee on future balance transfers (see terms)* balance transfer fee! if you had to pay in money when you filed then they are going to charge you interest for being late.

they are probably conducting an internal audit of all of your past returns right now, that is why you haven't gotten the notice yet. if they determine that you did this intentionally, which is likely, they'll access a punitive fine on top of the interest they'll charge you.

otherwise they might just send a warning. although it is illegal to file late, if you didn't owe them money they probably won't make a big deal out of it. just the same, they are probably auditing all of your recent returns. "a loan disbursement is an amount of money given to you when you finance the car.

if you received an additional ""principal disbursement,"" that usually means you refinanced the vehicle and took out some extra equity on top.

sometimes, if you switch your [car insurance](https://getjerry.com/car-insurance) to something less than full coverage or if you let your coverage lapse, the lender may add force-placed insurance to your loan and add the cost of the policy to the principal.

if you didn't do either of these, you'll need to call your lender to find out what the story is." 1. the expected pay-out on each policy is 250 * 1/90 + 12000 * 1/100 + 17000 * 1/400 = $165.  so that's what the premium would have to be in order to get a profit of 0.
 
2. the profit per policy is the premium the company receives minus the expected payout = 350 - 165 = $185.
 
3. the expected profit on 375 policies would be 375 * 185 = $69375 that is still 135 more than i'd pay you. it depends how much you would have to pay out on your current lease.
