Question

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? the greatest number of pens =? the greatest number of pencils =?

Answer 1

Answer:

Part A -  0.90(x + y) = 90 Part B - Pencils

Answer 2

Answer:

Part A: C) 0.90(x + y) = 90

Part B: Pens = 50 Pencils = 50

Step-by-step explanation:

PART A:

You want to find out how many pens and pencils you cn buy with that 90$ so you want to do

.75y+.15x=90

but you want to add .75+.15 which = .90

then you divide 90/.90

and that equals 100

then split it up and each gets 50

PART B:

Pens = 50

Pencils = 50
