For a school's annual budget, the total amount of money spent on supplies (s) and textbooks (t) cannot exceed $12,000. Which of the following inequalities represents this scenario?

A. s + t >= $12,000

B. s + t > $12,000

C. s + t < $12,000

D. s + t <= $12,000

Answer Explanation:

We can interpret ‘cannot exceed” as less than ‘<’. Therefore, in our inequality, the symbol < must be included. Now let’s convert the word problem into a mathematical inequality.

Money spent on supplies=s

Money spent on textbooks=t

Total money spent=money spent on supplies + money spent on textbooks

Total money spent = s+t

But the money spent cannot exceed $12,000. Then,

s+t < $12,000.
However the money spent can still be equal to $12000, as it has not exceeded it.

Therefore, the required inequality is s + t <= $12,000.

Therefore, the Correct Answer is D.

  • Q #1: Which of the following is the mean of the set data below? 30, 29, 28, 30, 24, 12, 26, 33, 25, 23

    A. 30

    B. 21

    C. 27

    D. 26

    Answer Explanation

    The mean is the total divided by the number of elements in the data set. From the given data set:

    Total=30+29+28+30+24+12+26+33+25+23=260

    Number of items, N=10

    Mean=total/N=260/10=26

    The mean is 26.

  • Q #2: A bakery sells three varieties of muffins. On a recent morning, the bakery sold 41 blueberry muffins, 27 banana nut muffins, and 20 black muffins. Estimate the total number of muffins sold.

  • Q #3: Pat deposits $600 in a savings account at a simple interest rate 6% per year for 5 years. How much money will Pat have earned in interest at the end of 5 years?

    A. $360

    B. $180

    C. $95

    D. $36

    Answer Explanation

    In the simple interest, we utilize the following formula to find the simple interest after a period of time in years.

    I=P*r*t

    I is the interest

    P=Principal or initial deposit

    r=rate

    t=time in years

    From the given problem, P=$600, r=6%=6/100=0.06, t=5 years. Then

    I=$600*0.06*5=$180

    After 5 years, Pat will earn an interest of $180.
