Question

the value of a share of stock decreases in value at a rate of $1.20 per hour during the first 3.5 hours of trading. write and solve an equation to find the decrease in the value of the share of stock during that time

Answer 1

Well since I don't know what the original value I'll label it as X. So your equation will start out as X - (1.20 x 1) which would be for every hour for a half hour just divide 1.20 / 2 to get your half an hour. (1.20 x 3) + 0.60. Should be easy if they want it in faction form than it would just be 1.20 x 3 1/2.

Hope this helps
