Method 1 - Evaluate Sale Price
•Sale Price = Regular $ - (Reg. $ x %)
•Sale Price = $24 - ($24 x 0.25) = d
$24 – d =
OR
Method 2 - Evaluate Sale Price
•100% -25% =75%
•Sale Price = $24 x 0.75) =

Method 1 - Sale Price
•Sale Price = Regular $ - (Reg. $ x %)
Sale Price = $80 - ($80 x 0.2) = d
$80 – d =
OR
Method 2 - Evaluate Sale Price
100% - 20% = 80%
Sale Price = $80 x 0.8 =

Divide into 3 rectangles
Find each rectangle’s
area
Find the sum of the
rectangles’ areas
OR
(13 x 7) – (4 x 8)=

• Convert feet to inches
1 foot = 12 inches
2 feet = 24 inches
• Evaluate the rectangle’s area using A = lw
A = 24” x 6”
