Answer:
y=|x -3| -1
Step-by-step explanation:
35% off means that now it costs 100%-35%=65% of the original price
<span>£78 ---- 65%
x------100%
x=78*100/65=120</span>£<span>
or
part/whole=0.65
78/whole=0.65
whole =78/0.65 =120 </span>£
It is 20 because if u divide 78 by 3.75 ( 3 3/4 ) than equals 20.8
When divided by 5, 3 subtracted from x divided by 2 equals to 6
