$80.00 x 0.20 = $16.00
$80.00 - 16.00 = $64.00
the hoodie costed $64.00
you were left with $16 to spare
(for x=0) 3 & (for x=4) 19
Let the partitions of the segment be 5k and 3k .
.
5k+3k = length of segment
Suppose the length of segment is y
8k = y
k = y/8
.
Hence ,
5k = 5(y/8)
3k = 3(y/8)
.
As the value of the segment wasn't given , it seems a bit complicated..
.
Hope u understand!
Yes you can and you do that by multiplying $42×1.30=54.60 and then $54.60×1.25=68.25
I don’t know the rest but number seven is n
