Answer:
a(c-b) = d
Use the distributive property, which states: x(y-z) = xy - xz
a(c-b) = ac - ab
ac - ab = d
Add ab on both sides
ac = d + ab
Divide both sides by a to isolate c
(If you would, please mark branliest, I'm one away from getting Expert
In order to have the variable by itself you have to add 20 to both sides. So your answer would be a=b+20. I hope this helps love! :)

➷ Figure out what you would need to do to get from 2.5kg to 1kg
You would need to divide by 2.5
Just divide the cost by this value:
2.5/2.5 = 1
1kg would cost £1.00
