Step-by-step explanation:

$............................................................... \n in \: other \: to \: get \: right \: ans \to \n you \: divide \: mass \: of \: jupiter \: by \: the \: mass \n \: of \: mercury : \: so \to \n ............................................................... \n jupiters \: mass = 1.898 { * 10}^(27) \: kg \n mercurys \: mass =3.3 * {10}^(23) \: kg \n their \: mass \: ratio \: is : \n = \frac{1.898 { * 10}^(27)}{3.3 * {10}^(23)} = 0.5751515152 * {10}^(4) = \n \boxed{5,751.515152} \n hence \: jupiters \: mass \: is \: approximatelty \: \n {6 * 10}^(3) \: times \: more \: than \: mercurys \: mass$

Tickets to a school dance cost $4 and the projected attendance is 300 people. For every $0.10 increase in ticket price, the dance committee projects that attendance will decrease by 5.Using formula R(4+.10t) (300-5t) where t is ticket price.

Determine the dance committee's greatest possible revenue. (Please show work as in #'s)

What ticket price will produce the greatest revenue? (Please show work as in #'s)

Answers

money made (R) = tickets sold * price of ticket
the number of $0.10 increases we make will be called t. so:
price of ticket = $4 + $0.10t
tickets sold = 300 - 5t
R = (4 + .10t)(300 - 5t)
R = 1200 + 10t - .5t^2
R = -1/2t^2 + 10t + 1200
to find the maximum, we have to find the roots of this function.
0 = -1/2t^2 + 10t + 1200
0 = -t^2 + 20t + 2400
0 = t^2 - 20t - 2400
quadratic formula
t = 20 +- sqrt((-20)^2 - 4(1)(-2400)) all over 2(1)
t = 20+-sqrt(400+9600) all over 2
t = 20+-sqrt(10000) all over 2
t = 20+-100 all over 2
t = -80/2 or t=120/2
t = -40 or 60
now find the average of these roots. this will find the "middle" of the parabola, which is where the vertex (maximum) will be.
-40 + 60 all over 2
20/2
10
the vertex is at t=10. plug this into the formula:
R = -1/2t^2 + 10t + 1200
R = -1/2(10)^2 + 10(10) + 1200
R = 50 + 100 + 1200
R = 1350
therefore, the number of 10 cent price increases should be 10, because that will lead to total profits of $1350, the maximum possible. the ticket price will be $5.

Step-by-step explanation:

Logan is a salesperson who sells computers at an electronics store. He is paid a $1.25 commission for every computer sale he makes and he also makes a guaranteed base pay of $80 each day. Write an equation for P, in terms of x, representing Logan's total pay on a day on which he sells x computers.

Answers

Final answer:

The equation for Logan's total pay on a day he sells x computers is P = 80 + 1.25x.

Explanation:

To represent Logan's total pay on a day he sells x computers, we need to consider his base pay and commission. Logan's base pay is $80 per day. Additionally, he earns a commission of $1.25 for each computer he sells. Therefore, the equation for P, representing Logan's total pay, can be written as:

P = 80 + 1.25x

#SPJ3

p=1.25x + 80

p is the pay and the 1.25 depends on how much computers he sells but he gets at least 80$ for his paycheck
