Y = mx + b
slope = m = 1/21, so we have
y = 1/2 x + b
The line passes through (2, 5), so we get
5 = 1/2 * 2 + b
5 = 1 + b
b = 4
The equation of the line is
y = 1/2 x + 4
Point (x, 3) has a y-coordinate of 3. We are looking for the x-coordinate.
y = 1/2 x + 4
3 = 1/2 x + 4
-1 = 1/2 x
x = -2
Let p be the amount of sales (in dollars) of phones.
Let c be the amount of sales (in dollars) of computers.
Equation 1: sales
p + c = 2100
the amount of all sales is 2100
Equation 2: commission
0.05p + 0.07c = 119
5% commission on phones plus 7% commission on computers totals to 119
