Put the argument value where the variable is, then evaluate.
For f(x), you want f(2).
f(2) = 2² + 1 = 4+1 = 5
For g(x), you want g(1).
g(1) = 3·1 +1 = 4
For [f(2) - g(1)] you want the difference of the above values.
[f(2) - g(1)] = [5 - 4] = 1
Answer:
This means the cost of the item to you is $57.75. You will pay $57.75 for a item with original price of $82.50 when discounted 30%. In this example, if you buy an item at $82.50 with 30% discount, you will pay 82.50 - 24.75 = 57.75 dollars.
Answer:
The sale is 5% off.
Step-by-step explanation:
- $25 regular price.
- $18.75 sale price.
You need to find the percentage that deducts $1.25 from the regular price. I start with 5% and work my way up from there until I find the answer.
So, <em>5</em><em>%</em><em> </em><em>of </em><em>2</em><em>5</em><em> </em><em>=</em><em> </em><em>?</em>
5% * 25 = 1.25
You needed $1.25, 5% gives you that.
Therefore, the answer is 5%.
