Employees at Unilever Company receive a set of hourly wage. The following is how the company wishes to change the rate:

$-$ Increase the rate per hour by R$1\mathrm{.}50$ if the number of hours worked $($hours$)$ is $40$ and the rate per hour$($rate$)$ is less than R$28\mathrm{.}50.$

$-$Increase the rate per hour by R$1\mathrm{.}20$ if there are $40$ hours and the rate rate per hour is R$28\mathrm{.}50$ or higher

$-$Increase the rate by $1\mathrm{.}5\%$ if the number of hours worked exceeds $40$ and the rate per hour is greater than or equal to R$28\mathrm{.}50$

$-$Reduce the rate per hour by R$0\mathrm{.}50$ per hour if the number of hours is less than $40.$

Using a do$-$while loop, write an algorithm in pseudocode to calculate the modified amount and the total pay if the hours are increased or reduced for all employees
