In a class of 20 students, 7 were wearing a white shirt. in the same class, 14 students had on blue jeans. eyewitnesses all stated that the suspect was in the class, and wearing both a white shirt and blue jeans. according to the laws of probability, what percent of the class could be the suspect?
a. 15% b. 25% c. 35% d. 45%
how to solve this problem?

I want to answer 15%

Step-by-step explanation:

As for  how to solve it I don't really know I would use process of elimination because the answer can't be so high that it's 45%  so that's out. Personally I think that 35% is pretty high to so my best educated guess would be between 25% and 15% . Sorry this isn't more helpful.

justin bieber ml.

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
