During a clothing store’s Bargain Days, the regular price for T-shirts is discounted by $5. There is a state sales tax of 5%, and the $5 discount is applied before the sales tax is calculated.a. Write an expression that shows the regular price r of a T-shirt minus the $5 discount.
b. Write a rule for the function p(r) that expresses the final price p of a T-shirt with the discount applied and sales tax added.
c. How much would you pay during Bargain Days for a shirt regularly priced at $15.50?
Answers
Answer:
A:
Let the regular price of the t shirt be = r
Let the total cost of the t shirt be = t
So, we can say :
B:
C:
Substituting r = 15.50
=>
= $11.025
b) p = ( r - 5 ) * 1.05
c) p = (15.5-5)*1.05 = 10.5 * 1.05 = $ 11.02

, by the number of servings in the box. So, 8 times 12 equals 96, therefore there are 96 crackers in a box.
2 servings = 16 crackers (2 x 8 = 16)
3 servings = 24 crackers (3 x 8 = 24)
12 servings = ? crackers
12 x 8 = 96
The answer is 96 crackers

The constant of variation is 1024.
What is function?
The function is defined as mathematics expression defines a relationship between one variable and another variable.
Given, y varies inversely with x,
y ∝ (1/x)
y= k. (1/x)
Let's take the constant of variation as k
y = k. (1/x)
k = yx
Substitute the vaules of x and y,
k = (-16) x (-64)
k = 1024
Hence, the constant of variation is 1024.

Answer: n = 4
Step-by-step explanation: To solve for n, we first isolate the term containing n which is 6n.
Since 8 is being subtracted from 6n,
we add 8 to both sides of the equation.
On the left, the -8 and +8 cancel out and on the right, 16 + 8 is 24.
So we have 6n = 24.
Now we can finish things off by just
dividing both sides of the equation by 6.
On the left the 6's cancel and on the right, 24 divided by 6 is 4.
So we have n = 4.
Answer:
n = 4
Step-by-step explanation:
6n - 8 = 16
Add 8 on both sides.
6n = 16 + 8
6n = 24
Divide 6 into both sides.
n = 24/6
n = 4
The value of n in the equation is 4.

Answer:
$1,120
Step-by-step explanation:
Interest I = PRT/100 where P = amount deposited, R = rate percent and T = time.
So I = (1000 * 4 * 3) / 100
= $120.
So the account balance is 1,120 dollars.
