Sandi buys 5 fewer packages of pencils than p packages of pens. Pencils costs $2.25 per package and pens costs $3 per package. What does the expression 3p + 2.25(p - 5) represent?

We are to determine what the expression 3p + 2.25(p - 5) represent.

let

packages of pens = p

packages of pencils = p - 5

cost of p - 5 packages of pencil = $2.25

cost of p packages of pen = $3

Total cost of pencil and pen = (p)3 + (p - 5)2.25

= 3p + 2.25(p - 5)

The expression 3p + 2.25(p - 5) represent total cost of pen and pencils sandi bought

3p + 2.25(p - 5) represents the total cost of the pens and pencils that Sandi bought.

Step-by-step explanation:

p = number of packages of pens

p - 5 = number of packages of pencils

2.25(p - 5) = cost of p - 5 packages of pencils

3p + 2.25(p - 5) represents the total cost of the pens and pencils that Sandi bought.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
