Answer:
The number of half-page advertisements is 4.
The number of Full-page advertisements is 11.
Step-by-step explanation:
According to the Question,
- Given, An advertising company charges $60 per half-page advertisement and $100 per full-page advertisement. Michael has a budget of $1340 to purchase 15 advertisements.
Let, 'x' be the number of half-page advertisements and 'y' be the number of full-page advertisements.
- Thus, 60x + 100y is the money charged, and given that he has a budget of $ 1340.
60x + 100y = 1340
- And, the number of advertisements is 15. So, the other equation is
x + y = 15
Now, We have Two Equations,
60x + 100y = 1340 and x + y = 15
- the solution of the system is Put x=(15-y) in Equation 60x + 100y = 1340
60 (15-y) + 100y = 1340
900 - 60y + 100y = 1340
40y = 1340 - 900
40y = 440
y = 440/40
y = 11 So, For x = 15 - y ⇒ 15-11 ⇒ x=4 .
- Thus, the number of half-page advertisements is 4 and The number of Full-page advertisements is 11 .

Answer:
The volume per dose that the patient should receive is 3.8 ml
Step-by-step explanation:
The physician ordered oncovin 2 mg/m² for chemotherapy treatment of a malignant tumor.
The adult's BSA (Body surface area) = 1.9m²
Hence, the amount of oncovin needed based on his body weight is:
2mg/1 m² = x mg/1.9m²
Cross Multiply
x mg = 2mg × 1.9
x = 3.8mg
We are told , oncovin is supplied:1 mg/ml
Hence:
This means
1 mg = 1 ml
3.8 mg = x ml
Cross Multiply
x ml = 3.8 ml
The volume per dose that the patient should receive is 3.8 ml
