An energy company’s stock price was $65.50 on Monday. On Tuesday, the price went up $1.50. On Wednesday, the price decreased from Tuesday’s price by $2.57. On Thursday, the price went up $2.25 from Wednesday’s price. Which of the following was the final price on Thursday?

A. $66.68

B. $65.79

C. $67.00

D. $64.43

Answer Explanation:

We are tasked to find the stock price on Thursday from the given information. Here, we need to find the stock of each day from the price increase or decrease. If the price increases, we add to the previous day’s price and subtract if the price decreases.

Monday’s stock price=$65.50

Tuesday’s stock price is Monday’s plus $1.50=65.50+1.50=$67.00

Wednesday’s stock price went down by $2.57 from Tuesday’s=67.00-2.57=$64.43

Thursday’s stock price went up by $2.25 from Wednesday’s =64.43+2.25=$66.68

From the above evaluation, the stock price on Thursday was $66.68

Therefore, the Correct Answer is A.

  • Q #2: -2/3, -0.5, -1.5, -4/9 Of the number listed above, which number is the greatest?

    A. -0.5

    B. -4/9

    C. -1.5

    D. -2/3

    Answer Explanation

    Before finding the greatest number from the data set, the numbers need to be in fraction form.

    -0.5=-5/10

    -1.5=-15/10

    The set of numbers becomes -2/3, -5/10, -15/10, -4/9

    Now the least common denominator for 3, 10, and 9 is 90, which will be used to multiplied by the given fractions as follows:

    -2/3*90=-60

    -5/10*90=-45

    -15/10*90=-135

    -4/9*90=-40

    From the above evaluations, the resulting numbers arranged from the smallest to the largest is -135, -60, -45, -40. Thus, the greatest number from the data set is -40, with a corresponding fraction of -4/9.

  • Q #3: Solve for A in the equation below. Diagram:  

    A. A = t(kr+P)

    B. A = (kr+P)/t

    C. A = P-kr/t

    D. A = kr-t/P

    Answer Explanation

    P-At=-kr

    Subtract P on both sides

    P-P-At=-kr-P

    -At=-kr-P

    Divide both sides by -t

    -At/-t=(-kr-P)/-t

    A=(kr+P)/t
