The table below shows how much lupe earns for each mile he walks for a library fundraiser. | miles walked | money raised ($) | | 0 | 50 | | 1 | 60 | | 2 | 70 | | 3 | 80 | let r represent the number of dollars he raises for the fundraiser. which equation represents how much lupe will raise for m miles? a. r = 50 + 10m b. r = m + 50 c. r = 5 x 10m d. r = 10 (m + 50)

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

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:
