STEP 1

Equation at the end of step

((14 • (x2)) -  7xy) -  (3•72y2)  

Equation at the end of step 2

 ((2•7x2) -  7xy) -  (3•72y2)

STEP 3

STEP 4

Pulling out like terms

4.1     Pull out like factors :

  14x2 - 7xy - 147y2  =   7 • (2x2 - xy - 21y2)

Trying to factor a multi variable polynomial :

4.2    Factoring    2x2 - xy - 21y2

Try to factor this multi-variable trinomial using trial and error

Found a factorization  :  (2x - 7y)•(x + 3y)

The cheapest available ticket for Super Bowl Ll on the secondary market costs
drek231 [11]

Answer:

He must work 52 days to pay for a single ticket.

Step-by-step explanation:

This question can be solved using proportions.

Per hour:

Joel earns $7.25 per hour, 20% of which is deducted for taxes. So without taxes, in each hour, he earns 100%-20% of 80% of this, so 0.8*7.25 = $5.8.

Per day:

He works 9 a.m. to 5 p.m. each day, so 8 hours a day.

For each hour, he earns $5.8.

So in a day, he makes 8*5.8 = $46.4

How many days he must work:

The ticket costs $2400.

He makes $46.4 a day.

So, to buy a ticket, he needs to work:

2400/46.4 = 51.7 days

Rounding up

He must work 52 days to pay for a single ticket.
