10. Mr. Ward bought a used car forx dollars. One year later the value of the car was 0.72x. Which
expression is another way to describe the change in the value of the car?
A 0.28% decrease
B 0.72% decrease
C28% decrease
D 72% decrease

D.

Step-by-step explanation:

0.72 = 72%

So that being the case, his car's value decreased by 72%

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
