PRACTICE TEST 1
1. Simplify: 3 q+ 6 n−1+2 q−4 n
2. Solve for y: 3 ( 5 y−4 ) +3 ( 1−3 y ) =3 (2 y−3 )
3. Solve for k: 10 k +59=2(5 k +26)
2 1 3
4. Solve for y: y − y = y+ 1
7 2 4
5. Solve for r: −1.05−0.21r =0.14 r +2.1
6. Solve for p: 3 p−7+ 7 p=4 p+ 45−7 p
7. At a private college in Massachusetts, the dollar per credit-hour cost C of tuition can be
approximated by
C=7.5 n+ 48
where n is the number of years since 2000 (that is n=0 corresponds to 2000, n=5
corresponds to 2005 and so on).
a. Solve for n in terms of C.
b. Based upon your equation from part (a), in what year could we expect the tuition
cost to be $168?
