stefanie bought a package of pencils for $1.75 and some erasers that cost $0.25 each. she paid a total of $4.25 for these items, before tax

The number of pencil package bought is 1

The number of eraser bought is 10 .

Step-by-step explanation:

Given as :

The price of the pencil package = $ 1.75

The price of the erasers = $ 0.25

The total money paid for the items = $ 4.25

Let The number of pencil package bought = p

And the number of eraser bought = e

So, According to question

The price of 1 pencil package = $ 1.75

And ,  total money paid for the items = $ 4.25

I.e ,  The price of 1 pencil package + ( The price of the erasers × number of eraser ) =  total money paid for the items

or, $ 1.75 + ( $ 0.25 × e ) = $ 4.25

Or,  ( $ 0.25 × e ) = $ 4.25 - $ 1.75

Or,  ( $ 0.25 × e ) = $ 2.5

∴  e =

I.e e = 10

So, number of pencil package bought = p = 1

And number of eraser bought = e = 10

Hence The number of pencil package bought is 1 , and The number of eraser bought is 10 . Answer

maximum area = xy = (16)(32) = 512 ft2
