Snowboard can be purchased for the lowest price from Store C offering 40% discount.

Step-by-step explanation:

We need to compare discounts of 3 stores and find the store selling snowboard lowest of them.

Store A: Sale of 30% off and a successive discount of 10% off.

The formula used for successive discount is = (x+y - xy / 100) %

here x = 30 and y = 10 so total discount is:

Total discount = (30 + 10 - (30*10) / 100) %

= (40 - 300/100) %

= (40 - 3) % = 37%

Original price = $189.59

Discount offered = 37% of $189.59

= 37/100 * 189.59 = $70.15

Selling Price = Original price - Discount offered

= $189.59 - $70.15

= $ 119.44

Store B: Sale of 20% off and a successive discount of 20% off.

The formula used for successive discount is = (x+y - xy / 100) %

here x = 20 and y = 20 so total discount is:

Total discount = (20 + 20 - (20*20) / 100) %

= (40 - 400/100) %

= (40 - 4) % = 36%

Original price = $189.59

Discount offered = 36% of $189.59

= 36/100 * 189.59 = $68.25

Selling Price = Original price - Discount offered

= $189.59 - $68.25

= $ 121.34

Store C: Sale of 40% off.

Original price = $189.59

Discount offered = 40% of $189.59

= 40/100 * 189.59 = $75.84

Selling Price = Original price - Discount offered

= $189.59 - $75.84

= $ 113.75

So, Store A Sale price is: $ 119.44

Store B Sale price is: $ 121.34

and Store C Sale price is: $ 113.75

So, Comparing them we found that snowboard can be purchased for the lowest price from Store C offering 40% discount.
