Question

Avery owns stocks in Ever Rise Corporation. The stock price increased by 120% over the past week. If the stock price was p last week, write two equivalent expressions that represent the current stock price and explain what their equivalence means. Substitute one or more variables into the expressions to prove them equivalent.

Answer 1

P(1.2) and p+ p(0.2) are equivalent expressions because they both equal to p(1.2).

P=2

Expression 1: P(1.2)=2(1.2)=2.4

Expression 2: P+p(0.2)= 2 + 2(0.2)= 2.4

2.4=2.4

Hope this helps!

Answer 2

Answer:

Expression 1. P+1.2p

Expression 2. 2.2p

Step-by-step explanation:

These 2 equivalent expressions state that increasing a value by 120% is the same as multiplying the original value by 2.2.

Example: assume that p=50. The first expression gives p+1.2p=50+1.2(50) =110. The second expression gives 2.2p=2.2(50)=110
