Answer 1

197.25 = .075 X. Solve for X.

For (37), Convert everything to oz. There are 16 oz in a pint and 32 oz in a quart.

For (38), use a common denominator of 36. 5/6 becomes 30/36 and 1/2 becomes 18/36.

For (29), assuming 5.75% is compounded annually, Dave's final balance is ( 18,500 ) ( 1.0575 )^3

For (30), take the difference, divide by the original sum, and convert to a percentage.

For (22), the depreciation is ( 24,146 )( .225 ). Subtract that value from the original cost to find the new value.
