20% = 0.2
Multiply $64 & 0.2 = $12.8
Subtract original price ($64) with discount amount ($12.8)
$51.2 is Discounted price. (Not including tax)

Answer:
yeshhh
Step-by-step explanation:
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
−3x+24+1=5
Step 1: Simplify both sides of the equation.
−3x+24+1=5
−3x+12+1=5
(−3x)+(12+1)=5(Combine Like Terms)
−3x+32=5
−3x+32=5
Step 2: Subtract 3/2 from both sides.
−3x+32−32=5−32
−3x=72
Step 3: Divide both sides by -3.
−3x−3=72−3
x=−76
answer
x=−76
