The glee club has $90 to spend on pens and pencils. each pen costs $0.75 and each pencil costs $0.15. let x represent the number of pens, and let y represent the number of pencils.

part a
select the equation that describes the number of club pens and pencils that the glee club can buy.

a. 0.15x + 0.75y = 90
b. 0.75x + 0.15y = 90
c. 0.90(x + y) = 90
part b
what is the greatest number of each type of writing tool that the club can buy?

greatest number of pens =

greatest number of pencils =

greatest number of pens =120

greatest number of pencils = 600

Step-by-step explanation:

Let x represent the number of pens

Let y represent the number of pencils.

Each pen costs $0.75

Cost of x pens = 0.75 x

Each pencil costs $0.15.

Cost of y pencils = 0.15y

Now we are given that The glee club has $90 to spend on pens and pencils.

So,

So,t the equation that describes the number of club pens and pencils that the glee club can buy is  

Part A)  

Part B )What is the greatest number of each type of writing tool that the club can buy?

Substitute y = 0

greatest number of pens =120

Substitute x = 0

greatest number of pencils = 600

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
