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

13.60 because you add the coupon discount back on and subtract tax cost and divide by 2

Solving the expression $\frac{4-5i}{2+3i}$ we get $-\frac{7}{13}-\frac{22i}{13}$

So, Option A is correct.

Step-by-step explanation:

We need to solve the expression: $\frac{4-5i}{2+3i}$

Multiplying and dividing by 2-3i

$=\frac{4-5i}{2+3i}*\frac{2-3i}{2-3i}\\=\frac{4-5i*2-3i}{2+3i*2-3i}\\=\frac{4(2-3i)-5i(2-3i)}{(2)^2-(3i)^2}\\=\frac{8-12i-10i+15i^2)}{4-9i^2}\\We\,\,know\,\, i^2=-1\\=\frac{8-12i-10i+15(-1)}{4-9(-1)}\\=\frac{8-15-12i-10i}{4+9}\\=\frac{-7-22i}{13}\\=-\frac{7}{13}-\frac{22i}{13}$

So, solving the expression $\frac{4-5i}{2+3i}$ we get $-\frac{7}{13}-\frac{22i}{13}$

So, Option A is correct.
