1 answer:

4 0

Plant cells having giant vacuoles which help them store more water than an animal cell. They also have chloroplasts allowing them to photosynthesize and make food, animal cells don't need chloroplasts. And lastly they have a cell wall which helps keep plant cells turgid or sturdy so they don't take in too much water and burst.

Getthere airlines currently charges $200$ dollars per ticket and sells $40{,}000$ tickets a week. for every $10$ dollars they in

Nataly_w [17]

Suppose GetThere Airlines increases their ticket price to $200+10n = 10(20+n)$ dollars. Then the number of tickets they sell is $40,000-1000n = 1000(40-n)$ . Therefore, their total revenue is

$$10(20+n)\cdot 1000(40-n) = 10000(20+n)(40-n) = 10000(800+20n-n^2).$$

This is maximized when $n=-\left(\frac{20}{2\cdot(-1)}\right)=10$ . Therefore, they should charge $200+10\cdot 10 = \boxed{300}$ dollars per ticket.

Alex Karev has taken out a $ loan with an annual rate of percent compounded monthly to pay off hospital bills from his wife Iz

Tom [10]

Answer:

the question is incomplete, so I looked for a similar one:

Alex Karev has taken out a $180,000 loan with an annual rate of 11% compounded monthly to pay off hospital bills from his wife Izzy's illness. If the most Alex can afford to pay is $3,500 per month, how long will it take to pay off the loan? How long will it take for him to pay off the loan if he can pay $4,000 per month?

PVIFA = $180,000 / $3,500 = 51.42857

PVIFA = [1 - 1/(1 + i)ⁿ ] / i = [1 - 1/(1 + 0.11/12)ⁿ] / 0.11/12

51.42857 x 0.11/12 = 1 - 1/(1 + 0.11/12)ⁿ

0.47143 = 1 - 1/(1 + 0.11/12)ⁿ

1/(1 + 0.11/12)ⁿ = 1 - 0.47143 = 0.52857

1 / 0.52857 = (1 + 0.11/12)ⁿ

1.89189 = 1.009167ⁿ

n = log 1.89189 / log 1.009167 = 0.2769 / 0.003963 = 69.87

n = 69.87 months

PVIFA = $180,000 / $4,000 = 45

PVIFA = [1 - 1/(1 + i)ⁿ ] / i = [1 - 1/(1 + 0.11/12)ⁿ] / 0.11/12

45 x 0.11/12 = 1 - 1/(1 + 0.11/12)ⁿ

0.4125 = 1 - 1/(1 + 0.11/12)ⁿ

1/(1 + 0.11/12)ⁿ = 1 - 0.4125 = 0.5875

1 / 0.5875 = (1 + 0.11/12)ⁿ

1.70213 = 1.009167ⁿ

n = log 1.70213 / log 1.009167 = 0.23099 / 0.003963 = 58.29

n = 58.29 months
