Question

mathematical modeling
part 1 of 2 1 2 trying to earn:
question 1: the parking lot holds 144 cars.
a) 38 cars leave the lot. choose the calculation for the number of cars n remaining.
n cars = 144 cars - 38 cars
b) c cars leave the lot. choose the mathematical model for the number of cars n remaining.
n cars = 144 cars - c cars
c) c cars leave the lot. write the mathematical model for the number of cars n remaining, leaving out the units.

question 2: perry saves 67 dollars per month.
a) choose the calculation that determines the number of dollars d that perry saves in 6 months.
select one
b) choose the mathematical model for the number of dollars d that perry saves in m months.
select one
c) write the mathematical model for the number of dollars d that perry saves in m months, leaving out the units.
(you can use \*\ for multiplication and \/\ for division.)

Explanation:

Step1: Solve Q1c: Remove units from model

$N = 144 - C$

Step2: Solve Q2a: Calculate total savings

$D = 67 * 6$

Step3: Solve Q2b: Generalize savings model

$D = 67 * M$

Step4: Solve Q2c: Remove units from model

$D = 67*M$

Answer:

Question 1c: $N = 144 - C$
Question 2a: $D = 67 * 6$
Question 2b: $D = 67 * M$
Question 2c: $D = 67*M$
