Ken bought 2 video games and 1 DVD for a total of $105. Jerome bought 1 video game and 4 DVDs for a total of $80. Which system of equations can be
used to find the cost, in dollars, of each video game (v) and each DVD (d) at the store?
Answers
Answer:
I think that the Linear system of equations can be used to find the cost.
Step-by-step explanation:
Answer:
2v + 1d = 105
and
1v + 4d = 80
Step-by-step explanation:
ken : 2v + 1d = 105
Jerome : 1v + 4d = 80
1v + 4d = 80 Try to get a video games by its self
- 4d -4d
1v = 80 - 4d
Plug into kens equation..
2(80 -4d) + 1d = 105
160 - 8d + 1d = 105
-160 -160
-7d = -55
/-7 /-7
d = 7.86 (rounded)
Plug into Jeromes equation
1(7.86) + 4v = 80
- 7.86 - 7.86
4v = 72.14
/4 /4
v = 18.035 (round = 18)

The cost of renting ice skates at a skating is $1.25. The rink charges $3.25 for each hour, x, of skating. Which graph best models this situation, where y is the total cost to go skating?
Answers
Answer:
Step-by-step explanation:
y = 3.25x + 1.25
1.25 is y-intercept
3.25 is the slope of a graph.
If x = 0, then y = 1.25
(0, 1.25)
If x = 3, then y = 3.25(3) + 1.25 = 11

If 400,000 tourists contribute $67 million to a local economy, how much would 600,000 tourists contribute?
Answers
Answer:
[tex]100.5\ \text{million}[/tex] is contributed by 600,000 tourists.
Step-by-step explanation:
Given that,
400,000 tourists contribute $67 million to the local economy.
We need to find how much would 600,000 tourists contribute.
400,000 tourists = $67 million
1 tourist = [tex](\dfrac{67}{400,000 })\ \text{million}[/tex]
So, 600,000 tourists contribution is :
[tex]600000\ \text{tourists}=(\dfrac{67}{400,000 })\times 600000\ \text{million}\\\\=100.5\ \text{million}[/tex]
Hence, [tex]100.5\ \text{million}[/tex] is contributed by 600,000 tourists.
