Answer:
The equation is 2x = 5y
Step-by-step explanation:
From the question, we are told that what is asked is 2/5 of the price for which each of the items are bought
y is the asking price, x is the original
Mathematically,
that would be;
y = 2/5 * x
y = 2x/5
Thus;
2x = 5y
2/1/3 or 7/3 you would just keep, change, flip s make it were its 5/3 times 7/5 then multiply and simplify. hope this helped
