Question

Wally buys a baseball card for $5, sells if for $6, buys the same card back for $7 the following days,

and then resells it for $8. How much profit or loss occurred in all these transactions combined?

Answer 1

3 dollars profit

Explanation:

if he has $5 b-card and sells it for $6 he gains a dollar. But if he buys it back for $7 then he lost $2 from his original price. In the end, he sells it for $8 so he gains a $3 profit. 8 - 5 = 3
