Two expressions each represent the sale price of the item are:
Expression B : 0.8p is correct
Expression D: p - 0.2p is correct
<em><u>Solution:</u></em>
The regular price of an item at a store is p dollars
The item is on sale for 20% off the regular price
Therefore,
Regular price = p dollars
Discount = 20 % of regular price
Therefore,
Discount = 20 % of p
Sale price = Regular price - discount price
Sale price = p - 0.2p
Thus Expression D: p - 0.2p is correct
On solving, sale price = p - 0.2p
Sale price = 0.8p
Thus expression B : 0.8p is correct

Answer:x =8.3
Step-by-step explanation:
Triangle ABG is similar to triangle DBE. This means that the ratio of the length of each side of ∆ABG to the length of the corresponding side of ∆DBE is constant. Therefore,
AB/DB = BG/BE = AG/DE
AB = 11
BG = 10 + x
Therefore,
11/6 = (x + 10)/10
Cross multiplying, it becomes
6(x + 10) = 11 × 10
6x + 60 = 110
Subtracting 60 from left hand side and the right hand side of the equation, it becomes
6x + 60 - 60 = 110 - 60
6x = 50
Dividing the left hand side and the right hand side of the equation by 6, it becomes
6x/6 = 50/6
x = 8.3 rounded up to the nearest tenth
The proportional relationship should require they y-intercept and is then 0 and the linear relationship should be in a straight line to be a linear! Hope this helps!
