Step-by-step 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%

Answer:
The age of Sue could be 7 years
Step-by-step explanation:
Jenny is 8 years older than twice her cousin Sue's age.
The first equation will be :
J = 8 + 2S ---------(1)
The sum of their ages is less than 32.
The second equation will be :
J + S < 32 ----------------(2)
Now rearrange both equations :
8 + 2S + S < 32
3S < 32 - 8
3S < 24
S < 24/3
S < 8
S = 7
The age of Sue could be 7 years.
