Candy is on sale for $0.75 each. you have a coupon for $0.25 off your total purchase. Write a function rule for the cost of n pieces of candy. A. C(n)0.25n-0.75
B. C(n)=0.75n-0.25
C. C(n)=1.0n
D. C(n)=0.75n

Answer:

X-intercept: To find the x-intercept, set y to 0 and solve for x.

-x + 2(0) = 4

-x = 4

x = -4

So, the x-intercept is (-4, 0).

Y-intercept: To find the y-intercept, set x to 0 and solve for y.

-0 + 2y = 4

2y = 4

y = 4/2

y = 2

So, the y-intercept is (0, 2).

Step-by-step explanation:

Answer:

$2.70

Step-by-step explanation:

Cost price = $6

Mark up percentage = 45%

Mark up amount = 45% × $6

                           = 0.45 × $6

                           = $2.70

Selling price = Mark up + cost price

                     = $2.70 + $6

                     = $8.70

Jermaine sells the shirts for $8.70 and makes a profit of $2.70.

Answer:

$2.70

Step-by-step explanation:

6*45% =2.70

Answer:

1,500 students

Step-by-step explanation:

Since in the question it is mentioned that 35% of students get less than 8 hours of sleep

And, there is a group of 2,000 students

Now the number of students who get eight or more hours per night sleep is

Suppose the total percentage be 100

Now the students more than 8 hours is

= 100 - 35%

= 0.75

And, the total students is 2,000 students

So, the number of students who get eight or more hours is

= 2,000 students × 0.75

= 1,500 students

The same is to be considered

2n^(3)+7n^(2)-2n-7

factor by grouping

2n^3 -2n  + 7n^2-7

2n(n^2-1) + (7(n^2-1)

factor n^2-1 out

(n^2-1) (2n+7)

factor (n^2-1)

(n-1) (n+1) (2n+7)
