(Original Price $425.4)

$328 × 30% = 98.4
328 + 98.4 = $426.40

100% - $328 - the price with the 30% off
130% - $?
10% - $?

Let's find by proportion:
1) $\frac{328*130}{100}$ = $426,4 - the price of the ski set without the EXTRA 30% off.

2) $\frac{426,4*10}{100}$ = $42,64 - the 10% off.

3) $426,4 + $42,64 = $469,04 - the original selling price of the ski set.

Olenka [21]

Answer:

Step-by-step explanation:

If you graph the equation f(x) = -16x^2+25x+15. You would need to pay attention to the x value which is somewhere in between 0.75-0.9.

Another way is to convert the equation into vertex form.

4 more than one third of a number n is 6. An equation is? The solution is n =?

harkovskaia [24]

Answer:

$\frac{1}{3}$ n + 4 = 6

Step-by-step explanation:

Given problem:

4 more than one third of a number n is 6

Unknown:

The equation = ?

Solution of the number = ?

Solution:

let the number = n

So, 4 more than one third of a number;

One third of n = $\frac{1}{3}$ n

4 more;

$\frac{1}{3}$ n + 4

is 6;

$\frac{1}{3}$ n + 4 = 6 (equation of the expression)

Let us now solve the equation:

$\frac{1}{3}$ n + 4 = 6

$\frac{1}{3}$ n = 6 - 4

$\frac{1}{3}$ n = 2

n = 6
