A man bought a calf for $200 and sold it for $250. What was his gain as a percentage of the
cost price?

Step-by-step explanation:

250 is 125% of 200

So,

He gained 25% in profit

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
