new price x cents

solve 10x = 12(15)

2. number of chickens --- x

number of pigs --- 41-x

solve : 2x + 4(41-x) = 100

3. number of people --- x

(5/6)x - 3 (3/4)x

4. let the number of year since Troy was born be x

Mrs. Grant = 20+6+x

Tess = 6+x

Carly = 4+x

Troy = x

solve : 26+x + 6+x + 4+x + x = 4(39)
