Question

Sergio had $500.00 saved for a family trip. Six weeks later he had saved $860.00. At what rate of change did Sergio savings grow

Answer 1

1% of $500 = $5

Total Saving from $500 to $ 860

`= (860)/(5) = 172 \\`

Now percentage of growth :-

`(172)/(500) * 100 \\ \\ (17200)/(500 ) = 34.4`

Hence, the rate of change Sergio savings = 34.4%
