Algebra I Exercises: Variables in Algebra
By B Horn
Directions and/or Common Information:
5 + x when x = 4
4x - 2 when x = 2
(m/2) + 7 when m = 10
(12/k) + y when k = 6 and y = 5
Directions and/or Common Information:
Determine the interest earned given the following figures.
Principle = $1,000
Rate = 3%
Time = 1 year
Principle = $22,000
Rate = 5.8%
Time = 6 months
Principle = $2,000
Rate = 12%
Time = 4 months
You place $10,000 in a bank account with an interest rate of 5.5%, and let it accrue interest, how much will you have at the end of 20 years (interest + principle)? How much will you have made in interest alone after 20 years? At the end of 50 years?

Directions and/or Common Information:
Calculate the distance traveled with the given variable. Round your answer to the nearest tenth.
rate = 5 mph and time = 10 hours
rate = 12 mph and time = 22 min
rate = 37 kph and time = 56 min
rate = 58 mph and time = 20 sec
