Answer:

  • a) j+c=310; j-c=40
  • b) (j, c) = (175, 135)
  • see attached
  • Jose earned $175; Camden earned $135

Step-by-step explanation:

Let j and c represent Jose's and Camden's earnings, respectively.

(a) One equation can be written for the total; another for the difference:

  j + c = 310 . . . . their total earnings

  j - c = 40 . . . . . the difference in their earnings

__

(b) It is convenient to add these two equations to eliminate c:

  (j +c) +(j -c) = (310) +(40)

  2j = 350

  j = 175

Then c can be found as ...

  c = j -40 = 175 -40 = 135

The solution is (j, c) = (175, 135).

__

(c) Using x for j, and y for c, we can use Desmos to graph the equations. The result is attached.

__

(d) Jose earned $175 over the summer; Camden earned $135.

without using a calculator decide which option is better value for money: 300g Jelly beans $5.80 or 500g Jelly beans $9.90
yarga [219]

Answer:

500g Jelly beans $9.90

Step-by-step explanation:

To know the values.

Let's know how much a gram will cost in each case

300g Jelly beans $5.80

1g = 5.8/300

1 g = 0.01933

500g Jelly beans $9.90

1g = 9.9/500

1g =0.0198

It's obvious that the second one has more value placed on it as it cost more per gram
