Approximately AED 150 is required to buy a box of highly nutritious peanut paste to treat 1 child with severe acute malnutrition for 10 weeks and AED 175 cover all the costs for the treatment of one child with severe acute malnutrition for 10 weeks. Calculate the total money required for peanut paste and treatment for 10 children for 10 weeks. Sam calculated as follows:
(150 x 10) +(175 x 10),whereas
Ahmed calculated as
10 x (150+175).Do you think both are correct ?

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)
