So let’s say your doing a problem like mine for instance: Shelly buys 3 cabinets worth 40.89$
and a chair for 27.98$
But you do all the work in your head
And you come out with something like 50.089 now in cents you can’t have anything beyond three numbers after the decimal so what would you do in this instance?

Round

Step-by-step explanation:

Round to the nearest cent (in this case 50 dollars and 9 cents)

150.65 is the answer

Step-by-step explanation:

You multiply 40.89 x 3 (122.67) then add 27.98.

And maybe do it on a paper

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
