Merlin wants to make more money selling fake beards this month than he did last month. all black beards in his shop cost the same amount of money, and all red beards in his shop cost $25. let b represent the number of black beards and r represent the number of red beards that merlin can sell to make more money than he made last month. 20b+25r > 350 according to the inequality, how much money did merlin make last month, and how much does each black beard cost?

We know that all black beards cost the same money

And all red beards cost $25

And B represents number of black beards

And R represents number of red beards

We have been given the inequality 20B+25R > 350 to show the target for this month.

The above inequality shows that Merlin needs to make more than 350, hence he made 350 last month

Further, it shows that B has been multiplied by 20, hence the black beard's cost was 20

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
