Find the simple interest.
Principal 200$
Rate of Interest12%
Time 2 years
The simple interest is $?

The answer is $248.

Step-by-step explanation:

You have to multiply 200*.12*2 which gives you 48, but you're asking for the total amount so you add 200 + 48 and you get $248.

$48.00

Step-by-step explanation:

The formula we'll use for this is the simple interest formula, or:

P= I × r × t

Where:

P equals principal amount, which is $200.00.

r equals interest rate, which in this case is 12% per year, or as a decimal, 12/100=0.12.

t equals time involved, which would be 2 years.

To find the simple interest, we multiply 200 × 0.12 × 2 to get that the interest is $48.00

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:
