Answer:
114
Step-by-step explanation:
You will need to multiply L x W and then add them all
Person: Number of prints Total Cost
Shelby 5 2.70
Allen 11 3.24
Denise 20 4.05
To solve for the variable cost:
11 - 5 = 6
3.24 - 2.70 = 0.54
0.54 / 6 = 0.09 per print
To solve for the fixed cost
0.09 x 5 = 0.45
2.70 - 0.45 = 2.25
y = 2.25 + 0.09x
y = 2.25 + 0.09(5) = 2.25 + 0.45 = 2.70
y = 2.25 + 0.09(11) = 2.25 + 0.99 = 3.24
y = 2.25 + 0.09(20) = 2.25 + 1.8 = 4.05
Answer:
Step-by-step explanation:
Let's solve:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 6x from both sides.
Step 3: Subtract 22 from both sides.
Step 4: Divide both sides by -2.
Answer:
They are increasing at the same rate.
