What is the equation of the graphed linear model?

It says that b represents Becky’s score and c represents Cathy’s score.
Becky’s score was 5 less than Cathy’s score, its equation can be written as :-
b = c - 5
It says that their combined score totaled 185, its equation can be written as :-
b + c = 185
So, correct pair of equations is b = c - 5 and b + c = 185.
If Becky’s score was 5 less than Cathy’s, then we would write:
b = c - 5
If Becky’s and Cathy’s scores add up to 185, then we would write:
b + c = 185
These are the two equations:
b = c - 5
b + c = 185

For this case we have to:
x: Represents the $ 0.25 game cards
y: Represents the $ 0.15 game cards
We have then:
From the second equation we have:
Substituting in the first equation:
So, I buy 8 game cards for $ 0.15
On the other hand we have:
So, I buy 12 game cards for $0.25
Answer:
Buy 8 game cards for $0.15
Buy 12 game cards for $0.25

Justin's eating rate is 1.5 hamburgers per minute. The correct option is C.
What is an expression?
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Justin is training for a hamburger-eating competition. He is eventually able to eat 15 hamburgers in 10 minutes.
Justin's eating rate will be calculated as,
Number of Hamburgers eaten by Justin in 10 minutes = 15
The number of hamburgers eaten by Justin in 1 minute,
ER = 15/10
ER = 1.5
Therefore, the eating rate is 1.5 hamburgers per minute. The correct option is C.
To know more about an expression follow
#SPJ2
Number of Hamburgers eaten by Justin in 10 minutes = 15
Then
The number of hamburgers eaten by Justin in 1 minute = 15/10
= 1.5
So option "B" is the correct option among all the options given in the question. It can seen from the deduction that Justin can eat 1.5 hamburgers in 1 minute. I hope the procedure is clear enough for you to understand.
