Answer:

x²y²+xy²+3+xy+2y²

Step-by-step explanation:

(2x²y²+x²y+xy²+3)-(x²y²+x²y²+x²y-xy-2y²)

1. remove the parentheses (when there’s - in front of an expression  in parentheses  change the sign of each term of the expression)

2x²y² + x²y + xy² + 3-x²y² - x²y² - x²y + xy - 2y²

2. eliminate the opposites

2x²y² + xy² + 3 -x²y² + xy +2y²

3. collect like terms

x²y² + xy² + 3 + xy + 2y²

At Ree Ski Center, the most people will pay for a neck warmer is $10. The manager of Ree Ski Center knows he needs a 30% markup
taurus [48]

Let x be the most the manager can pay the suppliers.

Then, we know from the information given in the question that the manager needs a 30% markup based on cost.

Therefore, the guiding equation will be:

x+\frac{30}{100}x\leq 10

because $10 is the most people will pay for a neck warmer.

Thus, the above equation will become:

x+0.3x\leq 10

1.3x\leq 10

x\leq \frac{10}{1.3}=7.69

\therefore x\leq 7.69

Thus, the most a manager can pay the suppliers for neck warmers and still keep the selling price at $10 is $7.69

Answer:

$2315.25

A= P(1+r)^t

substitute

A= 2000(1+0.05)^3

A= 2000(1.05)^3

A= 2000*1.157625

A= 2315.25

Hence the Amount is $2315.25
