Answer:
1770
Step-by-step explanation:
multiply the mass value by 1000
that is the easy way
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>£
The answer is B (Sorry for the bad handwriting.)
I set it up as an equation. 1/4x = 1/7x + 3. After you solve it out, it’s 28.
