x - 98

Step-by-step 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

you never say the total so we cant find the percentage used for petrol
