Answer:
We multiply by 340 x 0.35 then deduct afterwards.
So that = 119 and; 340-119 = 221
Sale price = $221
Step-by-step explanation:
When you stick to this way as same increase or decrease way forward, it applies to all increases and deductions and workings out for all percentage, you can then just remember to add 1 to 0.35 if it was a 35% increase, that way it will always help you remind yourself a similar method of decimalization and not converting can keep things central on solely what the percentage value represents and how it works that and each sum.
You would obviously for $400 and 2.5% interest fixed for 3 years f(x) 400 x 0.025^3 by adding the power also and this works and is applied for Standard Interest.
