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

3p = cost of p packages of pens

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: 370

step-by-step explanation:

remember use pemdas! there are no parentheses or exponents so lets move onto the first part of the equation: multiplication and division. first, lets break the first part of the equation up into something easier using the distributive property. 28 * 12= (20 *12) + (8*12) you know that 20*12 is 240 and 8*12 is 96. add them and you get 336. then, lets solve the last part of the equation (the last part of pemdas is addition and subtraction). 336 plus 34 is 370. hope this !

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
