1)solve for the rate (as a %). round to the nearest tenth of a percent when necessary.
$7.40 is what percent of $58.90?
2) solve for the base (in $). round to hundredths when necessary.
what is the base if the portion is $4,580 and the rate is 65%?
3). solve for the base. round to hundredths when necessary.

Imogene invested $8,000 in a bank account that pays 8 percent simple interest at the end of each year. her friend invested the same amount in stocks where the growth of the investment is represented as 2,000 times the square root of 2 less than the time lapsed in years. if y1 and y2 represent the amount earned in dollars and t is the time lapsed in years, which system of equations correctly represents the situation?
