Henrey bakes 84 bread rolls and fruit muffins. after giving away 18 rolls there are 5/6 as many rolls as muffins left. how many rolls does henrey bake?

48.

Step-by-step explanation:

Given, Henrey bakes 84 bread rolls and fruit muffins.

Let, Henrey baked x bread rolls, then he baked y fruit muffins. according to the second condition,

(x - 18) = 5/6 y

Now, solving these two equations,

y = 84-x

Or, x-18 = 5/6 (84-x)

Or, 6x- 108= 420-5x

Or, 11x= 528

Or, x= 48

Now, y= 84- 48= 36

Thus, Henry baked 48 rolls and 36 fruit muffins.

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:
