Hey there! I'm happy to help!
We see that if you add 5% to the original cost, we have $168 as our cost. This means that 105% of the original cost is 168. Let's set up an equation to find the original cost. Let's call our original cost c.
To turn a percent into a decimal, you divide by 100.
1.05c=168
We divide both sides by 1.05.
c=160
Therefore, the original cost was $160.
Have a wonderful day! :D

Area of the triangle is 20x(x - 1) sq. in
Step-by-step explanation:
- Step 1: Find the area of the triangle.

Area = 1/2 × base × height
⇒ Area = 1/2 × 4(x - 1) × 10x
= 20x(x - 1) sq. in
