If everything in a store is 20% off, and the discounted price of an item is $18.00, what is
jasenka [17]

The regular price is $22.5 if everything in a store is 20% off, and the discounted price of an item is $18.00

<h3>What is the percentage?</h3>

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

We have:

If everything in a store is 20% off, and the discounted price of an item is $18.00

Let's suppose the regular price is x

(100-20)% of x = 18

80x/100 = 18

x = $22.5

Thus, the regular price is $22.5 if everything in a store is 20% off, and the discounted price of an item is $18.00

Which inequality can be used to represent this problem? (HELP ASAP, IM TIMED)
Nadya [2.5K]

Propane costs $3.50 per hundred pounds,

and there is a $6 monthly delivery fee.  

A family has budgeted $85 for their propane this month.

Let  'x' hundreds of pounds can the family use without going over budget

Here family has budgeted $85 for their propane.

So the cost for Propane  = $ 3.5x

One month delivery fee $6

Therefore cost + delivery charge not exceed $85

So 3.5x + 6 ≤ 85

3.5x=85-6 =79

x = 22.57

Therefore 22 hundreds of pounds can the family use without going over budget

Consider the problem of finding the line of symmetry and vertex of the quadratic equation f(x) =x^2-8x+15 What is the error in t
Jet001 [13]
We are given the quadratic:

f(x)=x^2-8x+15, with a=1, b=-8, c=15.


We know that the x-coordinate of the vertex, which is the point where the line of symmetry passes through is 

                                  \displaystyle{  -\frac{b}{2a}.

Thus, the x-coordinate of the vertex is -\frac{b}{2a} =-\frac{-8}{2\cdot1}= \frac{8}{2}=4.

Thus, the line of symmetry is x=4.


Answer: <span>B. The line of symmetry should have been 4 instead of –4. </span>
