Answer:
number 10
dy/dx =(dy/dt).(dt/dx)
now find
dy/dt=4t-1. , dt/dx=1
so : dy/dx=(4t-1).(1)
dy/dx= 4t-1 ,we have x=t-3-----> t=x+3
subtitute at t
dy/dx= 4(x+3)-1=4x+12-1= 4x+11
65% of the total expenses is for marketing, in which 500,000 is the total.
First, change the percentage into decimal
65% = 65/100 = 0.65
Next, to find the amount budgeted for marketing, multiply the total with the decimal
0.65 x 500000 = 325000
$325000 is used for marketing
hope this helps
