Question

Who can help me with number 14

Answer 1

(Original Price $425.4)

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

Answer 2

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.
