The Chinese Buffet costs $9.95 a person. Johnny, his mother, and his father have dinner there, They receive a 25% discount. What is the discount? What is their bill after the discount?

$22.39

Step-by-step explanation:

Cost of all meals = $9.95 * 3 = $29.85

Amount of discount = 25/100 * $29.85 = $7.46

Bill = $29.85 - $7.46 = $22.39

hope it helps :)

the least common denominator is 40

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
