First, find out his wage
15 hours×$9= $135
Next find his commission
$7000×3.5%
=7000×0.035
=$245
Finally, add these together
$135+$245
=$380
He will make $380 selling electronics per week
Answer:
11.68
Step-by-step explanation:
23.76 + 1.49= 25.25
25.25 + 2.57= -27.82
39.50
-
27.82
=
11.68
Its important to remember that 23.76, 1.49, and 2.57 are all negative numbers that you have to add up and subtract it from $39.50 to get how much Isabella made.

Question:
Which expression is equivalent to 144^(3/2)
Answer:
1728
Step-by-step explanation:
The options are not well presented. However, this is the solution to the question.
Given:
144^(3/2)
Required:
Find Equivalent.
We start my making use of the following law of logarithm.
A^(m/n) = (A^m)^1/n
So,
144^(3/2) = (144³)^½
Another law of indices is that
A^½ = √A
So,
144^(3/2) = (144³)^½ = √(144³)
144³ can be expanded as 144 * 144 * 144.
This gives
144^(3/2) = √(144 * 144 * 144)
The square root can then be splitted to
144^(3/2) = √144 * √144 * √144
144^(3/2) = 12 * 12 * 12
144^(3/2) = 1728.
Hence, the equivalent of 144^(3/2) is 1728
