Sam earns $500 per week plus $25 for every trinket he sells. Let M represent the amount of money he made in a certain week and T represent the number of trinkets that he sold that week.

i) Give an equation that describes the situation.

ii) How many trinkets must he sell to earn $1000 in a single week?

i) M = 500 + 25T
ii) Sam must sell 20 trinkets.

i) M = 251
ii) Sam must sell 40 trinkets.

i) M = 500T
ii) Sam must sell 2 trinkets
DM

i) M = 25T
ii) Sam must sell 20 trinkets.

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.
