Answer:
x - 98
Explanation:
Given the question :
A stocks value decreased by 7 points each day for 2 weeks. Which numeric expression can be used to find out what the stock value was after the 2 weeks?
Let the initial value of the stock = s
Rate of decrease = 7 points per day
Number of days in a week = 7
Hence, 2 weeks = ( 2 * 7) = 14 days
Total decrease in stock over the 2 weeks period :
(Decrease per day × number of days)
(7 points × 14) = 98 points
Stock value after 2 weeks :
(Initial stock value - decrease in stock over the 2 weeks period)
= x - 98
