Question

question 1: the hospital has 108 beds.
a) 26 beds are filled with patients. choose the calculation for the number of beds n available for new patients.
n beds = 108 beds - 26 beds

b) b beds are filled with patients. choose the mathematical model for the number of beds n available for new patients.
n beds = 108 beds - b beds

c) b beds are filled with patients. write the mathematical model for the number of beds n available for new patients, leaving out the units.
n = 108 - b

question 2: eric publishes 5 books per year.
a) choose the calculation that determines the number of books b that eric publishes in 8 years.
--

b) choose the mathematical model for the number of books b that eric publishes in y years.
select one

c) write the mathematical model for the number of books b that eric publishes in y years, leaving out the units.
(you can use \*\ for multiplication and \/\ for division.)

Explanation:

Step1: Calculate total books in 8 years

Total books = books per year × years, so $B = 5 \times 8$

Step2: Model for Y years (with units)

Total books = books per year × years, so $B = 5 \text{ books/year} \times Y \text{ years}$

Step3: Model without units

Omit units, use * for multiplication: $B = 5 * Y$

Answer:

Question 2:
a) $B = 5 \times 8$
b) $B = 5 \text{ books/year} \times Y \text{ years}$
c) $B = 5 * Y$

For Question 1, the provided answers are already correct:
a) $\text{N beds} = 108 \text{ beds} - 26 \text{ beds}$
b) $\text{N beds} = 108 \text{ beds} - \text{B beds}$
c) $N = 108 - B$
