Please write this equation as <span>f(x) = −18 + x^2 − 3x

Rewrite it in descending order by powers of x: f(x) = x^2 - 3x - 18

Since the coefficient of the x^2 term is +, the graph opens UP.</span>

A car dealer's markup on every car they sell is 20%. For what price did the dealership buy a car that they sold for $18,600?

elena-s [515]

Answer:

buying price = $15,500

selling price 20% more than the buying price

let the buying price be 100% then;

selling price = 120%

120% = $18,600

100% = ?

(100 × 18600) ÷ 120

= $15,500

Given that,

Michael is leaving a 15% tip for his waitress.

To find,

What percent of the original price will he pay.

Solution,

Let the original price was 100%.

When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.

$115\%=\dfrac{115}{100}\\\\=1.15$

$\dfrac{115}{100}=\dfrac{23}{20}$

So, this is the required solution.
