Total area is 30 by 50 feet=1500 ft^2
So per square foot charges are 2.99$ and 200 additional
1500×2.99+200=4685$
And another charging 19.99$ per square yard
1 yard = 3feet
30 feet=10 yard
50 feet=50/3 yard
Area=50/3×10=500/3=166.66yards^2
So they will charge 166.66×19.99=3331.66+500= 3831.66$
So comapny B is cheaper and best deal

Answer:
T4 = -2°F
Step-by-step explanation:
Given the following data;
Current temperature = 10°F
Constant, K = 3°F
Time, t = 4 hours
In four (4) hours, we have;
T = kt
Substituting into the equation, we have;
T = 3 * 4
T = 12°F
T4 = current temp - new temp
T4 = 10°F - 12°F
T4 = -2°F
Therefore, the temperature it will be in 4 hours is - 2°F.
Answer:
Step-by-step explanation:
a)y=-2x+8
y=4x-7
solution
b)y=x-4
y=3x-2
solution
c)x – 3y = -3
x – 3y = 6
no solution
d)3x +y = 3
6x + 2y = 6
infinite.
