The United States Postal Service charges more for boxes whose combined length and girth exceeds 108 in. The length of a package is the length l of its longest side; the
girth is the perimeter of the cross section, 2w + 2h. What is the maximum volume of a
package with a square cross section ( w = h) that does not exceed the 108 in.
standard?
Maximum volume V =

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:

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

irrational, cannot
