If 12 dozen were bought for $90 that means each CD was bought at the price of $0.66
If he sold all 60 of the CD's for 5 for $12, he'd make $144.
Subtract the income by the original buying price to find his profit. $144 - $90
The peddler made $54 profit.
For this you use A=Pe^(rt)
A=furutre amount
P=present amount
e=natural base
r=rate in decimal
t=times in years
A=?
P=5000000
r=0.04
t=30
A=5,000,000e^(0.04*30)
A=5,000,000e^(1.2)
A=16600584.613683
You could solve it ( without a graph) in 2 easy ways :
1 use the equation that you have written in pencil and solve for y
y=3=-x+4
y=-x +1
Or you could use the point slop form after you find the y intercept y=mx+b
-3=4(-1)+b
b= 1
So the answer would be y= -x +1
Hope this help of it does feel free to give the brainliest
The positive factor of -72 is [72].
