Finding the change in y/change in x=the slope, we get
(13-11)/(-4-(-2))=2/-2=-1. Therefore, the equation is y=-1*x+b. Plugging it into (-4, 13), we note that 13=4+b and b=9 by subtracting 4 from both sides, making the equation y=-x+9. Plugging it into A, we get that
1 (y , the second value) = -x+9. Subtracting both sides by 9, we get 1-9=-x and -8=-x. Multiplying each side by -1, we get x=8

A flower vendor sells roses for 50 cents each. how much does she pay per flower if she makes $6.00 on every $20 worth sold

kkurt [141]

We are given

selling price of one flower is $0.50

so, $SP=0.50$

Let's assume

she sold 'n' flowers to get $20

so, total amount she get after selling 'n' flowers is

$=0.50*n$

$=0.50n$

This is supposed to be $20

so, we can set it equal to 20

$20=0.50n$

now, we can solve for n

we get

$n=40$

we are given

she makes $6.00 on every $20 worth sold

so, we can find cost of 40 flowers is 20-6

total cost is 14

or cost of 40 flowers is $14

now, we can find cost of one flower

$CP=\frac{14}{40}$

$CP=0.35$

so, cost of each flower is 35 cents...............Answer

7% is the same as 7/100 so take

and then add that to the original price

10.50 + 149.99 = 160.49
