Answer:6.5
Step-by-step explanation: If you simplify (3 x 2) into 6, it will leave 6+6x=45. So if you subtract 6 on both sides it will cancel out the one on the left and make 45 into 39. So now you have 6x=39 so now you just divide 6 on both sides and get 6.5.

<u>Second Discoun</u>t
20% off means we paid 80%. We know we paid $328 of some price.
I can now cross-multiply by multiplying numerator and denominator from each ratio.
I now solve for y by dividing by 80.
y=410
The price after the first discount was $410.
<u>First Discount</u>
We will repeat the steps above with $410. 18% off means we paid 82%.
I can now cross-multiply by multiplying numerator and denominator from each ratio.
I now solve for y by dividing by 82.
y=500
The original price was $500.
