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?

greatest number of pens = ?


greatest number of pencils = ?

Answer 1

Answer:

part A; B and Part B;  pencils

Step-by-step explanation:

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

.75y+.15x=90

pens=50

pencils=50

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

Answer 2

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 0.15

Then we have total cost = cost of pens + cost of pencils

= $0.75x+0.15y$=90

Hence option B is right

For finding out the greatest number of each type of writing tool, we can make the other 0 and find out

Hence maximum x = $\frac{90}{0.75} =120$

maximum y =$\frac{90}{0.15} \\=600$
