Answer:
$6.65
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 7.5 × 20/100
Discount = 7.50 x 0.20
You save = $1.50
Original Price - Discount
7.50 - 1.50=
$6.00
You still have to add the tax:
5.75 = 0.0575
0.0575 x 7.50=
$0.65
Add $0.65 to your discount and you get the answer
$6.65
B. 6.25
C. 75.00
D. 125.00
Solution:
Making list makes your work easy.
Suppose monthly income of a person is 10,500 $. Amount spent on housing finances is $45,00, paying car loan per month is $ 200, tuition charges for their son and daughter in different activities that they do is $ 200.And once in a month they go for excursion .The amount spent on excursion is $ 250. Find the total amount spent by that person in a month.
Solution:
So, we will make the list of the amount spent on various activities by that person , then we can find the total amount spent in month by that person.
1. Amount spent on housing finances= $ 4500
Amount spent on car loan per month = $ 200
Amount spent on tuition charges for their son and daughter in different activities=$ 200
Amount spent on excursion =$ 250
Total money spent by that person in different activities=$ 4500 +$ 200+$ 200+$ 250= $ 5,150
So, we have made list here to solve this problem, which made our work easier.
Suppose the housing expenses is $ 4500 , which includes different items that the family buys for their household expenses, for that we can make list also.

An environmental agency studying the effects of drought on a lake found that the water level decreased at a constant rate during the first few months of the drought. When the agency began its research, the depth of the lake was 346 feet. The table represents the agency’s susequent observations about the lake's depth.
Which equation represents the depth of the lake, y, based on the number of weeks passed, x?
y = -0.6x + 346
y = -1.2x + 346
y = -0.6x
y = -1.2x
Answer:
Option A
Step-by-step explanation:
The given function is a linear function therefore rate of change of this function will be the slope of the given line.
Since this line passes through two points ( 0,1 ) and ( 0.5 0 )
the slope of the line =
slope =
= ( -2 )
Therfore, Option A will be the answer.
The rate of change of function is,
m = - 2
We have to given that,
A function is shown in figure.
Since, The rate of change of linear function is slope of line.
Here, Two points on the line are (1, - 1) and (0, 1)
Since, The equation of line passes through the points (1, - 1) and (0, 1)
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (1 - (-1)) / (0 - 1)
m = 2 / - 1
m = - 2
So, The rate of change of function is,
m = - 2
