At a fair it cost $1.50 per child admission and $4.00 per adult admission. one day a total of 2,200 people attended the fair and the total admission collected was $5,050. how many children and how many adults attended.

700 adults and 1500 children .

Step-by-step explanation:

First, write the two equations letting c=children and a=adults :

c+a=2200   1.50(c)+4.00(a)=5050

Now, use substitution ... c=2200−a 1.50(2200−a)+4.00(a)=5050

Simplify ... 2.5a=1750 a=700 Using the first equation ... c=2200−a=2200−700=1500 In summary, there were 700 adults and 1500 children . hope that helped

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

its adding 5.5 each time
