Which question can be represented by the equation ? × 1/8 = 3.

im confused on the sentence.

"Peter makes $1/8 for every pencil he sells. Yesterday he made $3 by selling pencils, how many of them he sold? "

Step-by-step explanation:

Modeling of Reality

Sometimes we have a real situation and we want to provide a mathematical model to explain it. But what if we have the model and need to imagine what the situation could be? It calls for our imagination and tries to figure out such a problem, given the answer

We can see a question mark multiplying the fraction 1/8 to produce a result of 3. This is a common proportion problem. This is my approach

"Peter makes $1/8 for every pencil he sells. Yesterday he made $3 by selling pencils, how many of them he sold? "

If we solved this question, we have to replace the ? for 24 and say Peter sold 24 pencils and made 24(1/8)=$3

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
