Answer:

1) $361.25

2) $280

Step-by-step explanation:

1) $425 * 0.85 = $361.25

If you purchase something that is 25% off then you would only be paying 85% of the cost. 85% in decimal form is 0.85

2) $350 * 0.80 = $280

Similarly, 20% off means you pay 80% of the cost. 80% in decimal form is 0.80


Hope this helps! Please mark brainliest! Have a great day!

Which functions have the same rate of change?
Anestetic [448]

Answer:

Option 3

Step-by-step explanation:

All equations are in slope-intercept form. y=mx+b

The 'm' is the slope.

The 'b' is the y-intercept.

The slope is also known as the rate of change. So, we would have to look at what replaces 'm' and select two equations that have the same rate of change.

<em>Let's look over the equations:</em>

<h3>Equation A:</h3>

y=0.3x-6

In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.

<h3>Equation B:</h3>

y=3x-8

In this equation, 3 replaces 'm', so the rate of change for this equation is 3.

<h3>Equation C:</h3><h3>y=0.3x+4</h3>

In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.

<h3>Equation D:</h3><h3>y=0.03x+1</h3>

In this equation, 0.03 replaces 'm', so the rate of change for this equation is 0.03.

Equation C and equation A have 0.3 as the slope. Since the question asks for two equations that have the same rate of change, the answer would be Equations A and C, or Option 3.

1. Nuri wants to determine the average distance she travels each day in her car. She records the odometer reading each morning f
Firdavs [7]
The average is the total number of miles run dived by the number of days.


The total number of miles is the difference of the last reading ( 11,477) less the initial reading (10,150) = 11,477 - 10,150 = 1,327 miles.


The number of days is 7.


The the average is:

average = number of miles run / number of days = 1,327 miles / 7 days =  189,6 miles / day.


Answer: 189,6 miles / day.
