Ms. rodriguez purchased markers to use on her class whiteboard. she bought a total of 16 markers and three times as ma
red markers,
set up the two equations that can be used to find the number of markers of each color that ms. rodriguez purchased.
• let constraint 1 refer to the equation that represents the total number of markers.
• let constraint 2 refer to the equation that describes the ratio of the number of blue markers to red markers.
only constraint
would be met if ms. rodriguez purchased 3 red markers and 9 blue markers.
only constraint
would be met if ms. rodriguez purchased 6 red markers and 10 blue markers.

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
