Answer:
$33
Step-by-step explanation:
The travel allowance that Helen Ming receives is $220
The income tax rate is 
The amount she has to pay is calculated by multiplying the tax rate by the travel allowance.

We simplify to obtain

Therefore Helen Ming has to pay $33 form her benefit.
So sale price=100%-40%=60%
48=60%
one easy way is to manipulate the numbers
20 times 5=100 so we will get 60 to 20 then muleitply remember ot do the same thing to both sides
48=60%
divide both sides by 3
16=20%
multiply both sides by 5
80=100%
the origonal price=$80
The answer is 6.75 inches
The best answer would be -10.2n -1
I got this answer by doing both same numbers, so the ones with variables i did and got -10.2 n
then I did -3+2 and got -1
So that is the answer, hope it helps!!!
