Answer:
C(p) = p*50 + 300
Step-by-step explanation:
Using the names:
Clm: cost of labor and materials
Crm: fixed cost on rent and equipment
p: number of phones
and Ct: total cost
the ecuation would be number of phones times the cost and material plus the fixed cost, something like this
p * Clm + Crm = Ct
on the example we have all the data except the rent and equipment cost (the fixed cost) so thats what we need to solve
producing 3 phones its
3 *¨50 + Crm = 450
Crm = 450 - 150 = 300
so replacing in the above formula the equation would be
C(p)=p * 50 + 300
Answer:
Step-by-step explanation:
The equation representing the growth of the plant after x weeks is expressed as
y = 0.2x+2
Where
x represents the number of weeks.
y represents the height of the plant after x weeks in inches.
A.
The height of the plant after week 3 was about 2.6 inches. We can check by substituting x = 3 into the equation. It becomes
y = 0.2 × 3 + 2 = 2 + 0.6 = 2.6 inches. It is correct.
B is incorrect.
C.
The height of the plant after week 9 was about 3.8 inches. We can check by substituting x = 9 into the equation. It becomes
y = 0.2 × 9 + 2 = 2 + 1.8 = 3.8 inches. It is correct.
D is incorrect
