After a 25% discount...means that u paid 75%
so 75% of the original cost is 18.50...
0.75x = 18.50.....with x being the original cost
x = 18.50 / 0.75
x = 24.666 rounds to 24.67 <==
Answer:
Hey there!
We can write this equation, where x is the hourly rate and y is the fixed fee.
4x+y=270
7x+y=420
4x+y=270
-7x-y=-420
-3x=-150
x=50
4(50)+y=270
200+y=270
y=70.
The fixed fee is G. $70.
Let me know if this helps :)
Answer: More detail please.
Include any multiple choices.
(a)
Given:
is in xy plane and 
is in the direction of k.
|a|=6 units, |b|=3 and θ = 90°
|a × b| = |a| × |b| sinθ
= |a| × |b| sin90°
= 6 × 3 × 1
|a × b| = 18
(b)
Let 
is perpendicular to both 
.
In this case,
x-component of 
is positive.
y-component of is negative.
z-component of is zero.
