select one
b) p people move away. choose the mathematical model for the number of people n remaining
select one
c) p people move away. write the mathematical model for the number of people n remaining, leaving out the units

question 2: spencer rented 700 apartments.
a) choose the calculation for the rate a at which spencer rents apartments per year if it took him 12 years to rent them.
select one
b) choose the mathematical model for the rate a at which spencer rents apartments per year if it took him y years to rent them.
select one
c) write the mathematical model for the rate a at which spencer rents apartments per year if it took him y years to rent them, leaving out the units
(you can use \*\ for multiplication and \/\ for division.)

Explanation:

Question 1

Step1: Calculate remaining people (a)

Subtract movers from total.
$N = 580 - 115$

Step2: Model for variable movers (b/c)

Subtract P from total population.
$N = 580 - P$

Question 2

Step1: Calculate rental rate (a)

Divide total apartments by years.
$A = \frac{700}{12}$

Step2: Model for variable years (b/c)

Divide total apartments by Y years.
$A = \frac{700}{Y}$

Answer:

Question 1:
a) $580 - 115$
b) $N = 580 - P$
c) $N = 580 - P$

Question 2:
a) $\frac{700}{12}$
b) $A = \frac{700}{Y}$
c) $A = 700 / Y$
