1 dozen of calculators = 12 calculators
Selling calculators at $20 for every 3 calculators is the same as selling calculators at $80 for every 12 calculators, or 1 dozen.
b=number of dozen of calculators bought, or 6
s=number of dozen of calculators sold, or 6
p=amount of profit
65(b)-80(s)=|p|
65(6)-80(6)=|p|
390-480=|p|
-90=|p|
90=p
The profit on six dozen calculators is $90.

Answer:

$90

Step-by-step explanation:

First: 20x12=240

240/3=80

65(6)-120(6)=p

390-480= -90

90 is the profit

If you vertically compress the absolute value parent function, F(x) = |x|, by
marshall27 [118]

The current function equation is  Y=1/3|x|

---------------------------

The meaning relative f(x) = is the absolute value and is weighted by a factor 3 vertically.

If a constant (say a) multiplies the function, the parent will be extended vertically.

We have below vertical extension and compression conditions.

A > 1 = > spread vertically

0 < < 1 = > compression vertically

Therefore we will subtract the entire feature by 1/3 for vertical compression by a factor of 3.

The equation for the current function is then Y=1/3|x|
