Answer:
$135.01
Step-by-step explanation:
A mark up of 100% means that the price was doubled.
58.7*2=117.4
To add sales tax to a price (p) you need to do p+(sales tax * p)
117.4+.15(117.4)
135.01
You multiply 124 (0.065) which gets you 8.06. You then add 8.06 to 124 and you get 132.06.
Answer:
The equation of the line is;
y = 3x + 18
Step-by-step explanation:
We want to write the equation of the line through (-9,-9) and (-6,0)
we start by calculating the slope of the line
m = (y2-y1)/(x2-x1) = (0+ 9)/(-6+9) = 9/3 = 3
The general equation of the line is;
y = mx + c
y = 3x + c
To get c, we use any of the points
we substitute for example -6 for x and 0 for y
0 = 3(-6) + c
c = 0 + 18 = 18
So the equation of the line is;
y = 3x + 18
Answer:
The answer is x=27/28
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
