I came in super late

Allushta [10]

Since we know that 1/4 is equal to 25%, or 0.25 in decimal form, we are able to work with 0.75 in the expression.

We are told to use j as the original price of the jeans, so we can set up the expression:

$j-0.25j$

to represent the cost of the jeans with the discount.

Then to simplify, we simply take out j as a common factor, and solve what's in the parentheses:

$j(1-0.25)$

$j(0.75)$ or $0.75j$

Using this equation, we can solve for the b part of the question. If the pair of jeans originally costs $60, plug in 60 to where j is in the expression:

$0.75j$

$0.75(60)=45$

Therefore, the cost of the jeans after the discount is C) $45.

How can the average rate of change be found using a discrete graph?

nekit [7.7K]

In general, the average rate of change of f (x) on the interval a, b is given by f(b) – f(a) / b – a. The average rate of alteration of a function, f (x) on an interval is well-defined to be the variance of the function values at the endpoints of the interim divided by the difference in the x values at the endpoints of the interval. this is also known as the difference quotient that tells how on average, the y values of a function are changing in connection to variations in the x values. A positive or negative rate of change is applicable which match up to an increase or decrease in the y value among the two data points. It is called zero rate of change when a quantity does not change over time.
