Mrs. Smith paid $6.60 for a dozen donuts. What is the cost per donut in dollars and cents?

1.82 dollars per donuts

Step-by-step explanation:

you divide 12 by 6.60

which gets you 1.81 repeating so you round to the nearest cent

which is 1.82 per donut

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
