Answer:

0.75x + 0.15y = 90

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, 0.75x + 0.15y = 90

So,t the equation that describes the number of club pens and pencils that the glee club can buy is  0.75x + 0.15y = 90

Part A)  0.75x + 0.15y = 90

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

0.75x + 0.15y = 90

Substitute y = 0

0.75x = 90

x = \frac{90}{0.75}

x = 120

greatest number of pens =120

Substitute x = 0

0.15y= 90

y = \frac{90}{0.15}

y = 600

greatest number of pencils = 600
