Answer:
video game: $29.50
DVD: $10
Step-by-step explanation:
Let d = price of one DVD, and let v = price of 1 video game.
"A bundle of two video games and three DVDS can be purchased for $89.00."
2v + 3d = 89
"A bundle of one video game and two DVDS can be purchased for $49.50."
v + 2d = 49.5
We have two equations in two unknowns, so we can solve them as a system of 2 equations.
2v + 3d = 89
v + 2d = 49.5
Rewrite the first equation.
Multiply both sides of the second equation by -2 and write it below the first equation.
Add the equations.
2v + 3d = 89
(+) -2v - 4d = -99
---------------------------
-d = -10
d = 10
Now we substitute 10 for d in the second original equation and solve for v.
v + 2d = 49.5
v + 2(10) = 49.5
v + 20 = 49.5
v = 29.5

Step-by-step explanation:
Given:
Diver name Number of dive Number of boxes
Sam 11 33
Wet Suit Willy 18 81
Deep Diving Dan 26 104
Find:
Who found the most treasures per dive
Computation:
Sam's per dive collection = 33 / 11 = 3 boxes
Wet Suit Willy's per dive collection = 81 / 18 = 4.5 boxes
Deep Diving Dan's per dive collection = 104 / 26 = 4 boxes
Wet Suit Willy found the most treasures per dive.
