Sarah took the advertising department from her company on a round trip to meet with a potential client. including sarah a total of 5 people took the trip. she was able to purchase coach tickets for $380 and first class tickets for $1080. she used her total budget for airfare for the trip, which was $4000. how many first class tickets did she buy? how many coach tickets did she buy?

Sarah bought 2 coach tickets and 3 first class tickets.

Step-by-step explanation:

Let c and f represent the numbers of coach and first class tickets purchased.  Then c + f = 5, so that c = 5 - f.

The pricing equation is therefore

$380c + $1080f = $4000.  Subbing 5 - f for c, we get the revised equation

380(5 - f) + 1080f = 4000.

After simplification, this becomes:

-380f + 1080f = 2100, or

700f = 2100.

Then f = 3 and c = 5 - f = 5 - 3 = 2.

Sarah bought 2 coach tickets and 3 first class tickets.

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
