Deonte invested 2at his bank for 10 years if he earned 13 what was the interest rate the bank gave him

The interest rate the bank gave Deonte is 6.5%.

Solution:

Given, Deonte invested 200000 at his bank for 10 years  

He earned 130000  

We have to find what was the interest rate the bank gave him.

Now we know that, simple interest

So, by substituting our values in above formula,

Interest rate 20000 = 130000

Interest rate 2 = 13

Hence, the interest rate given by bank is 6.5% to Deonte.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

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:
