A)
x=sales
4/100 x + 400≥460
b)
Solve the inequation:
4/100 x+400≥460
lest common multiple= 100
4x+40000≥46000
4x≥46000-40000
4x≥6000
x≥6000/4
x≥1500
answer: the minimun amount tha se will needs to sell is $1500.
Answer:
35 hotdogs
Step-by-step explanation:
You are running a concession stand at a basketball game. You are selling hotdogs and sodas.
Let the number of hot dogs be represented by x
The number of soda be represented by y
You sold a total of 87 hotdogs and sodas combined
x + y = 87
x = 87 - y
Each hotdog cost $1.50 and each soda cost $0.50. At the end of the night you made a total of $78.50.
Hence we have the equation:
$1.50 × x + $0.50 × y = $78.50
1.50x + 0.50y = 78.50
Substitute 87 - y for x
1.50(87 - y) + 0.50y = 78.50
130.5 - 1.50y + 0.50y = 78.50
Collect like terms
- 1.50y + 0.50y = 78.50 - 130.50
-1.00y = -52
y = -52/-1
y = 52 sodas
How many hotdogs did you sell?
Using the equation:
x = 87 - y
x = 87 - 52
x = 35 hotdogs
Hence, you sold 35 hotdogs
Answer:
False
Step-by-step explanation:
Zero is not a natural number.
I'd start by finding the x and y intercepts. If x = 0, then y = 18/4 so your coordinate would be (0, 18/4). When y = 0, then x = 18/5 so your coordinate would be (18/5, 0). Now, if you solve it for y and pick a value for x, like 1 for example, you could find you y very easily.
. Choosing x = 1, you would get y = 5/4 + 18/4 and y = 23/4. So your 3 coordinates could be (0, 18/4), (18/5, 0), and (1, 23/4)
