Reggie picked 3 3/4 quarts of blueberries and 4 1/3 quarts of raspberries at a fruit farm. about how many total of berries did he pick?

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

so, converting firstly the mixed fractions to improper fractions and then "adding".
