Roger's Electronics sells a variety of computers and other electronic devices. During the month of July, Roger's sold the following numbers of computers: Dates Total Computers Sold
July 1-4 68
July 1-12 204

Part A:
Assuming that the proportional relationship between computers sold and days continues, write an equation that shows the amount of computers (y) sold per day (x) in July.

Part B:
How many computers were sold during the entire month of July (31 days long)?

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:

5.25 ounces

step-by-step explanation:

divided 3/4 and 6

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
