Adeep-sea diver must descend and ascend in a short time to equalize pressure on her body. if the diver rises to the surface to quickly, she may suffer from a physical condition called "the bends". suppose the diver descends to the bottom in 3 steps of 12 feet each. write and simplify an expression to describe the divers change in elevation.

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

she would want to sell 10 full-year subscriptions and at least 9 half-year subscriptions to get a total of at least $300.
