X= 20
1.8x +12=48
48-12 = 36
36/1.8 = 20
The total salary was $656.64 including his hourly wage and his commission.
The amount of total sales was $3,344.
6% * $3,344 = 0.06(3344) is his commission.
His wage is $12 per hour, so he earns 12h for working h hours.
656.64 = 12h + 0.06(3344)
Let's factor the following polynomial to find the roots:
x2-13x + q = 0
Factoring we have:
(x-12.5) * (x + a)
Where,
-12.5 + a = -13
a = -13 + 12.5
a = -0.5
We now look for the coefficient q:
q = -12.5 * a
q = -12.5 * (- 0.5)
q = 6.25
The polynomial will then be:
x2-13x + 6.25 = 0
Its roots are:
x1 = 12.5
x2 = 0.5
Answer:
The other root and the value of the coefficient are:
0.5 and 6.25 (Respectively)
= 5.45 × 1.5/0.025
= 5.45 x 60
= 327
Answer= 327
Hope this helps! :)
