Tom wishes to purchase a property that's been valued at $300,000. He has 25% of this amount available as a cash deposit, and require a mortgage for the remaining amount. The bank offered him a 25-year mortgage at 2% interest with monthly payments. Calculate the total interest Tom will pay.

Total interest is $149,528.31

Step-by-step explanation:

In the first place,Tom already has 25%*$300,000=$75,000

This implies that the mortgage amount=$300,000-$75,000=$225,000

In order to ascertain the total interest Tom would pay it would necessary to know the total amount Tom would have to pay back in respect of the mortgage since the total interest is the difference between total amount repayable less the present worth of the mortgage of $225,000

FV=PV*(1+r)^n

FV is the future worth of the mortgage i.e total amount repayable

PV is the present worth of $225,000

r is the rate of interest of 2% yearly,but  0.17%  monthly(2%/12)

n is the number of month it would take Tom to repay the mortgage i.e 25 years multiplied by 12 300 months

FV=$225,000*(1+0.17%)^300=$ 374,528.31  

Total interest=$ 374,528.31-$225,000=$149,528.31

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
