You have two loans, for 2 years each. the total interest for the two loans is $138. on the first loan, you pay 7.5% simple interest on a principal of $800. on the second loan, you pay 3% simple interest. what is the principal for the second loan?

$300

Step-by-step explanation:

We are told that you have two loans, for 2 years each. The total interest for the two loans is $138. On the first loan, you pay 7.5% simple interest on a principal of $800.

Let us find the amount of interest for 1st loan.

, where,

I = Amount of interest,

P = Principal amount,

r = Interest rate in decimal form,

t = Time

Let us convert our given rate for 1st loan in decimal form

Now let us find the amount interest for 2nd loan.

Let us convert our given rate for 2nd loan in decimal form

Upon substituting our given values for 2nd loan in interest formula we will get,

Therefore, the principal amount for the 2nd loan is $300.

three-fourths of an hour

36÷48=0.75

0.75=

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
