Answer: 7 cookies
Step-by-step explanation:
232 - 57 = 175
175 / 25 = 7
To solve this problem, we have to figure out a rule for the function. We are told that it is a two-step rule, so it is most likely the input multiplied by a coefficient plus a constant. Let’s let the input be represented by the variable x and the output be represented by the variable y. Using our knowledge, we can see that the outputs are close to triple the input, so we set up the preliminary equation:
y = 3x + b,
where b is a constant. If we want to solve for b, we must plug in one of our input/output pairs. If we plug in (5,16), we get the following:
16 = 3(5) + b
16 = 15 + b
1 = b
Then, we should substitute in this value into our equation and check our work.
y = 3x + 1
If we plug in the other points, this equation yields a true statement, so we know it is correct.
Hope this helps!

D: 7
Step-by-step explanation:
1.75 (7) + 4.50
12.25 + 4.50
= 16.75
16.75 < 20
Answer: Total cost to make 12 pennants is $52.5.
Step-by-step explanation:
Since we have given that
There is a rectangle and a triangle.
Length of rectangle = 1 ft
Width of rectangle = 3 ft
So, Area of rectangle is given by
Base of triangle = 1 ft
Height of triangle = 1 ft
So, Area of triangle is given by
So, Total area of the pennants will be
Number of pennants = 12
Cost per square foot of pennant = $1.25
So, Total cost for 12 pennants is given by
Hence, Total cost to make 12 pennants is $52.5.
