Keith bought a pair of jeans at a discounted price of $91.00. The original price of the pair of jeans was $130.00. If Keith got
the same discount on a t-shirt that originally cost $23.00, what is the discounted price of the t-shirt?
2 answers:
So first step would be to find the percent Keith got off for his jeans. To do that subtract 130-91 to get a difference of 39, then multiply 39 by 100 which is 3,900 and then divide by 130 which will give you 30. Which means Keith got 30% off his jeans. So, to find how much his shirt cost if he got 30% off you would multiply the original price, 23 by 0.3 or 30 percent and you get 6.9 then subtract 23-6.9 to get 16.1. So Keith bought his shirt for $16.10.

Answer: Answer with Step-by-step explanation:
Since we have given that
Cost of party per person = $20.
Let the number of friends be 'f'.
Let the cost of party be 'p'.
According to question, our equation becomes
p= 2f
So, if p = 100, then f = p/2 = 100/2 = 50 if f = 10, then, p = 2f = 2 • 10 = 20 If p = 300 then, f = 300/2 = 150, If f = 20, then, p = 2f = 2 • 20 = 40 So, Table as follows:
Number of friends cost of party
50 100
10 20
150 300
20 40
The true statement about the function f(x) = -x² - 4x + 5 is that:
- The range of the function is all real numbers less than or equal to 9.
The domain of a function is the set of given values of input for which the function is valid and true.
The range is the dependent variable of a given set of values for which the function is defined.
- The domain of the function: f(x) = -x² - 4x + 5 are all real number from -∞ to +∞
For a parabola ax² + bx + c with the vertex
- If a < 0, then the range is f(x) ≤
- If a > 0, then the range f(x) ≥
- Here; a = -1,
The vertex for an up-down facing parabola for a function y = ax² + bx + c is:
Thus,
- vertex
= (-2, 9)
Range: f(x) ≤ 9
Therefore, we can conclude that the range of the function is all real numbers less than or equal to 9.
