# Got Lanyards?

### By: Laasya Madana

## Part I

1. $35 for the first lanyard, $5 for each additional

2. $65 for the first lanyard, $3 for each additional

3. $95 for the first lanyard, $1 for each addiotional

## Which One is Best?

I plugged them into the equation and figured out what the total cost would be.

Here are my results.

Scheme 1:

35+5x=y As you can see, when 10 lanyards are

x=9 ordered, the most affordable

35+5x9=y scheme is the first one.

35+45=y

80=y

Scheme 2:

65+3x=y

x=9

65+3x9=y

65+27=y

92=y

Scheme 3:

95+x=y

x=9

95+9=y

104=y

Results:

As you can see, when 10 lanyards are

ordered, the most affordable

scheme is the first one.

## Part II

Scheme 1:

35+5x=y

x=49

35+49x5=y

35+245=y

280=y

Scheme 2:

65+3x=y

x=49

65+3x49=y

65+147=y

212=y

Scheme 3:

95+x=y

x=49

95+49=y

144=y

## Part III

Scheme 1:

35+5x <_ 500

5x<_465

x<_93

The amount we could buy from Offer 1 is 93 or more.

Scheme 2:

65+3x<_500

3x<_435

x<_145

The amount we can buy from Offer 2 is 145 or more.

Scheme 3:

95+x<_500

x<_405

The most we could but from Offer 3 is 405 or more.
