1) Solve for x: -¾ x + 2(-x+ 3) < 10 (2 pt)
2) A family of 2 adults and 3 children go to the county fair that sells raffle tickets for 75¢ each. Admission price is $5 per child and $8 per adult. Let n be the number of raffle tickets bought.
2a) Write a function in the form of C(n) to describe the cost of this family going to the county fair. (2 pts)
2b) What is the domain of this function? (1 pt)
2c) What is the range of this function? (1 pt)
2d) If the family wants to spend at most $35, what is the maximum number of raffle tickets that they can buy? You must write the inequality equation to get full credit (2 pts)

2) A family of 2 adults and 3 children go to the county fair that sells raffle tickets for 75¢ each. Admission price is $5 per child and $8 per adult. Let n be the number of raffle tickets bought.
2a) Write a function in the form of C(n) to describe the cost of this family going to the county fair. (2 pts)
2 adults = $8*2 = $16.
3 children = $5*3 = $15.
$15+$16 = $31
Raffle tickets (n) = $0.75 each.
C(n) = $0.75n + $31
The rest of the answers to this problem (and the answers to the rest of the problems) should be obvious.
