write the inequality in standard form for this situation: the CRHS science departmenr can spend no more than $2700 on textbooks this year. the department needs to buy both biology text books which cost $57 each and chemistry textbooks which costs $72 each
A. 57x+72y>2700
B.57+72y<=2700
C.57x+72y<2700
D.57x+72y>=2700
Let x represent the number of biology textbooks and y represent the number of chemistry textbooks.
Since the biology textbooks cost $57 each and the department needs to buy x number of them, the cost of the biology textbooks is 57x.
Similarly, since the chemistry textbooks cost $72 each and the department needs to buy y number of them, the cost of the chemistry textbooks is 72y.
The total amount that the department can spend on textbooks is $2700.
Therefore, the inequality in standard form for this situation is:
57x + 72y ≤ 2700
So, the correct answer is B. 57x + 72y ≤ 2700
