3 bottles of juice
6.72/3 = $2.24 < amount paid for each bottle
11 bottles of juice
24.86/11 = $2.26 <amount paid for each bottle
9 bottles of juice
20.25/9 = $2.25 < amount paid for each bottle
16 bottles of juice
35.68/16 = $2.23 < amount paid for each bottle
*the best buy would be to get 16 bottles for $35.68*10 bars of soap
23.20/10 = $2.32 < amount for each bar of soap
16 bars of soap
36.48/16 = $2.28 < amount for each bar of soap
13 bars of soap
29.51/13 = $2.27 < amount paid for each bar of soap
12 bars of soap
27.60/12 = $2.30 < amount for each bar of soap
*the best buy would be to get 13 bars of soap for $29.51*hope this helps :)
I think it is the first answer I just now did this problem yesterday z.Y<1/4x-1
Answer:
8
Step-by-step explanation:
401.92 divided by 16 = 25.12
25.12 divided by 3.14 is 8
Given : tan 235 = 2 tan 20 + tan 215
To Find : prove that
Solution:
tan 235 = 2 tan 20 + tan 215
Tan x = Tan (180 + x)
tan 235 = tan ( 180 + 55) = tan55
tan 215 = tan (180 + 35) = tan 35
=> tan 55 = 2tan 20 + tan 35
55 = 20 + 35
=> 20 = 55 - 35
taking Tan both sides
=> Tan 20 = Tan ( 55 - 35)
=> Tan 20 = (Tan55 - Tan35) /(1 + Tan55 . Tan35)
Tan35 = Cot55 = 1/tan55 => Tan55 . Tan35 =1
=> Tan 20 = (Tan 55 - Tan 35) /(1 + 1)
=> Tan 20 = (Tan 55 - Tan 35) /2
=> 2 Tan 20 = Tan 55 - Tan 35
=> 2 Tan 20 + Tan 35 = Tan 55
=> tan 55 = 2tan 20 + tan 35
=> tan 235 = 2tan 20 + tan 215
QED
Hence Proved
It would be $20.40 because 20% off of $28.00 is $22.4 - $2.00= $20.40
