Marlin and Dori eat algae on their way to find Nemo. For
every 8 ounces of algae that
Dori eals Marlin consumes 5
ounces of algae. If they eat 91
ounces of algae, how many
ounces of algae does Marlin
eat?

I'm not sure but I think the answer is 455

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
