b. Write and explain two different expressions for the price of the item after the second month. Your expressions should involve 300,20, and 25. Include a math drawing as part of your explanation.

Answer 1

initial price = $300

1 month later 1,2(300) = $360

2 months later 1.25(1.2)(300) = 1.25(360)=450

= 1.5(300) = $450
