Hello people who is this talking to me!?!?!?

Ben is three times as old as samantha, who is two years older than half of michel's age. if michel is 12. how old is ben?

Solve with work both bert and ernie received an increase in their weekly salaries. bert's salary increased from $520 to $520. ernie's salary went from $580 to $645. find the percent of increase for each salary. what was the larger of the two percents ?

If the cost to mail a package is an initial $5 and $0.28 for every pound the total cost to mail a package was $11.27, how much did the package weigh?
