Answer:
∠ ABC = 90°
Step-by-step explanation:
∠ ABC is the angle in a semi circle and is right, that is
∠ ABC = 90°
Let p represent the computer’s original price.
A. 0.25p = p – 180
B. 0.75p = p + 180
C. 0.25(p – 180) = p
D. 0.75p = p − 180
We are required to find equation which compare the price of computer in both stores.
The equation that represents the expression is 0.75p = p - 180 and the value of the computer's original price is $720
Let
p = the computer’s original price.
Store A = 25% off the original price.
= p - (25% of p)
= p - (25/100 × p)
= p - (0.25 × p)
= p - 0.25p
= 0.75p
Store B = p - 180
The equation:
Store A = store B
0.75p = p - 180
0.75p - p = -180
-0.25p = -180
divide both sides by -0.25
p = -180 / -0.25
p = $720
