For item 2:
The Net Price Rate = 276 / 460 = 0.60 = 60 % (answer).

Item 4 Net Price Rate = 675.11 / * 100 / 987 = 68.4%. (answer).
Item 5 Item's Net Price = 987 * 0.675 = $666.23 (answer).
Item 7 Net price Rate = 2945* 100 / 4750 = 62%. (answer).
Item 8: First find the list place $x:
0.90* 0.80 * 0.70x = 252 ( the 0.90 , 0.80 and 0.70 come from 100 - 10% = 1 - 0.10 = 0.90 and so on)
0.504 x = 252
x = $500
Answer is List Price = $500 and Net Price Rate = 50.4%.
Item 10 List price = 2890.65 / 0.35 = $8259. (answer)
Answer:
He paid $9 twelve times
12× 2= 24 days
Step-by-step explanation:
1st day = $16.60
3rd day=$ 9 (i.e for every 2days afterwards)
5th day=$ 9
Yuri pays : 124.60
124.60-16.60
= $108.00
After paying the first day he paid 108.00
108.00÷ 9 = 12
He paid $9 twelve times
12× 2= 24 days
