Answer:
approximately 3 hours time stock A will be the same price with Stock B
Step-by-step explanation:
Stock A increases at $ 0.05 per hour
stock A at 9 a.m = $ 15.75
stock A at 12 noon = $ 15 .75 + $ 0.05 * 3
= $ 15.75 + $ 0.15 = $ 15.90
stock A in the next three hours again will be = $ 15.90 + $ 0.05 * 3
= $15.90 + $ 0.15 = $ 16.05
Stock B at 12 noon = $ 16.53
stock B decreases at $ 0.13 per hour so in the next three hours stock B will be
= $ 16.53 - $ 0.13 * 3
= $ 16.53 - $0.39 = $16.14
