A plane is moving north st 120 km/h
Answer:
X = 0 4 8 12
Y = 10 7 4 1
Step-by-step explanation:
Given:
Cost of one T shirt = $15
Cost of one sweater = $ 20
To find :
The graph that will represent both number of T-shirts and sweatshirts = ?
Solution:
Let the number of t-shirts be x
The number of sweaters be y
They want to rise a found of $200
Then the equation to represent this situation is
15x + 20y = 200
By trial and error method
15(12) + 20(1) = 200
15(8) + 20(4) = 200
15(0) + 20(10) = 200
15(4) + 20(7) = 200
Answer: (a)350 + 0.05x ≥ 600 (b) $5000
Explanation:
Fixed Salary = $350
Variable = 5% on sales
Let x the sales amount
Equation: 350 + 0.05x ≥ 600
350 + 0.05x ≥ 600
0.05x ≥ 600 - 350
0.05x ≥ 250
x ≥ $5000
Y=x^-3...................
