This year, a small business had a total revenue of $72,900. If this is 35% more than their total revenue the previous year, what was their total revenue the previous year? =$___

Therefore there revenue was $540,000.

Step-by-step explanation:

Let their total revenue last year be x

so

35% of x = $72,9000 - x

or, 35/100 × x = 729000 - x

or, 7x/20 = 729000-x

or, 7x = 20(729000-x)

or, 7x = 1458000- 20x

or, 7x + 20x = 14580000

or, 27x = 14580000

or, x = 14580000/27

so, x = $540,000

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:
