Sam is in charge of food supplies for a camp this summer. the 7-day camp will be attended by 30 children. in a previous cam, 275 pounds of food were served to 24 children over 5 days. how many pounds of food should sam order so that there is enough food for the 7-day camp this summer? give your answer to the nearest pound.

Sam should order 480.9 ≈ 481 pounds so that there is enough food for the 7-day camp this summer

Step-by-step explanation:

Given :

The 7-day camp will be attended by 30 children.

In a previous cam, 275 pounds of food were served to 24 children over 5 days

To Find: How many pounds of food should Sam order so that there is enough food for the 7-day camp this summer?

Solution :

24 children served food for 5 days = 275 pounds

24 children served for 1 day =

1 children served for 1 day =

                                          = 2.29 pounds

So, 30 children served for 1 day = 2.29*30 = 68.7 pounds

So, 30 children served for 7 days = 68.7*7 = 480.9 pounds

Hence, Sam should order 480.9 ≈ 481 pounds so that there is enough food for the 7-day camp this summer

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
