Read the following information, and answer the questions below: Salvidore and Thomas are both writing a paper for school. At the start of the week, Salvidore has already written 4 pages, and he continues to write 2 pages a day. Thomas has already written 2 pages at the start of the week, but he writes faster at a rate of 2.5 pages a day. Write a linear equation for Salvidore

Write a linear equation for Thomas

After how many days will they have written the same number of pages? How many pages will they have written at this point?

Using your answer from above, write this information as an ordered pair:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
