Answer:

25%

Explanation:

Amount Kedwin has for the purchase = $150

Total cost of purchase :

Item cost =. $175

Shipping cost = 0.1 * 175 = 17.5

Total cost =. $(175 + 17.5) = $192.5

Smallest sale rate in other to afford the item:

At 10%

(1 - 0.1) * 192.5 = $173.25

At 20%

(1 - 0.2) * 192.5 = $154

At 25%

(1 - 0.25) * 192.5 = $144.375

Hence, smallest sale rate needwd is 25%
