(Original Price $425.4)

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.

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  

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
