Answer:
The final cost price of the cellphone is $121.5
Step-by-step explanation:
The marked price of the cell phone = $150
Now, sale percentage on the marked price = 10%
Now, 10 % of 150 = 
⇒The sale discount on the marked price = $15
So, the selling price of cellphone = Marked Price - Sale discount
= $150 - $15 = $135
Now, the second discount offered on $135 is 10%
10 % of 130 = 
⇒The additional sale discount on the selling price = $13.5
So, the final cost of cellphone = Selling Price - Additional Sale discount
= $135 - $13.5 = $121.5
Hence, the final cost price of the cellphone is $121.5
Additive inverse is what you add to a number to get zero.
So, by definition, the additive inverse of (-8 + 3i) would be <em>(8 - 3i)</em>.
Y=20x+100
The +100 is because her parents are paying $100 for the bike, the 20x is for the $20 per week she will save
