Find the total amount and total interest after six months if the interest is compounded every quarter. Principal = ₹10{,}000 Rate of interest = 20 \%=20%equals, 20, percent per annum

Amount = $11025

Interest = $1025

Step-by-step explanation:

Amount in a compound interest is given by

where P is the principal, R is the rate and T is the time.

The interest is compunded quarterly i.e. 4 times a year. Hence its rate per quarter will be 20% ÷ 4 = 5%.

The principal is compunded for six months which is 2 quarters. Therefore, T = 2.

The interest is A - P = 11025 - 10000 = $1025

where is the rest of the

step-by-step explanation:

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:
