27 times 6
27*6=162
Julia made $162 that morning
I think that’s right
Answer:
There is a decrease of 0.75 sales per day
Step-by-step explanation:
Given:-
- The price of item = p
- The number of sales = x
- The relationship between "p" and "x" is given below:
4p+4x+2px=56
Find the rate at which x is changing when x=2, p=6, and dp/dt=1.5 The rate at which x is changing is [ ] sales per day
Take the time derivative (d/dt) of the entire given expression and apply chain rule on d/dt ( 2px ). Since both "p" and "x" are only functions of time "t":
d/dt
4p+4x+2px=56
4*dp/dt + 4*dx/dt + 2*(x*dp/dt + p*dx/dt)=0
Use the given values x=2, p=6, and dp/dt=1.5 to determine dx/dt
4*1.5 + 4*dx/dt + 2*(2*1.5+6*dx/dt)=0
6+4dx/dt + 2*(3+6dx/dt)=0
6+4dx/dt + 6+12dx/dt=0
12+16dx/dt=0
12=-16dx/dt
dx/dt= 12/-16
= -0.75
Answer:
5(8 - 2t) = 2 + 16(4 + t)
open the brackets;
use 5 to mulitiply (8 - 2t) = 40 - 10t
use 16 to mulitiply (4 + t) = 64 + 16t
then we have 40 - 10t = 2 + 64 + 16t
collect like terms
40 - 2 - 64 = 16t + 10t
-26 = 26t
divide both sides by 26
t = -1
