Step-by-step explanation:
<u>Step 1: Define</u>
0.4(12 - 3x) = 0.3(12x - 16)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 4.8 - 1.2x = 3.6x - 4.8
- Add 1.2x on both sides: 4.8 = 4.8x - 4.8
- Add 4.8 on both sides: 9.6 = 4.8x
- Divide 4.8 on both sides: 2 = x
- Rewrite: x = 2
Question 1:
All provided options would give the best deal on an item
Answer: Option d [all of the above]

Step-by-step explanation:
3.38 × 
is the scientific notation of 3,380,000
I = Prt
Interest on CD = 0.0425 x $1,800 = $76.5
Interest on savings = 0.0275 x $1,800 = $49.5
Difference of interest on CD and Interest on savings = $76.5 - $49.5 = $27
Therefre, he will earn $27 more if he invest in a CD rather than in a savings.
