A. 0.15x + 0.75y = 90 B. 0.75x + 0.15y = 90 C. 0.90(x + y) = 90Part BWhat is the greatest number of each type of writing tool that the club can buy?greatest number of pens = greatest number of pencils =

Accepted Solution

A:
Answer:Step-by-step explanation:Given that total amount available is 90$x represent the number of pens, and  y represent the number of pencils. cost of each pen is 0.75 and cost of each pencil is 0.15Then we have total cost = cost of pens + cost of pencils= [tex]0.75x+0.15y[/tex]=90Hence option B is rightFor finding out the greatest number of each type of writing tool, we can make the other 0 and find outHence maximum x = [tex]\frac{90}{0.75} =120[/tex]maximum y =[tex]\frac{90}{0.15} \\=600[/tex]
