Answer:
min = -9
max =3
Step-by-step explanation:
C = x-3y
x ≥0
x≤3
y≥0
y≤3
The minimum will be be when x is smallest and y is at its max
x =0 and y = 3
C = 0 - 3(3)
C = 0-9 = -9
The minimum is -9
The maximum occurs when x is largest and y is smallest
x =3 and y = 0
C = 3 - 3(0)
C = 3-0 = 3
The max is 3
Answer:
15 - 3 (expression)
15 - 3 = x (equation)
Step-by-step explanation:
Keywords
linear equation, variables
Step 1
Define the <u>variables</u>
Let
x-----> number of erasers
y-----> total cost
we know that
------> this is the <u>linear equation</u> that represent the situation
therefore
the answer is
20% of 500----20% of 100----5% of 100
