Answer:
Ronnie's annual salary this year = $38,850
Explanations:
Ronnie's annual salary last year = $37,000
Percentage increase in Ronnie's salary = 5%
Increase in Ronnie's salary = 5% of 37000 = 5/100 x 37000
Increase in Ronnie's salary = $1850
Ronnie's annual salary this year = Ronnie's annual salary last year + Increase
Ronnie's annual salary this year = $37000 + $1850
Ronnie's annual salary this year = $38,850
