Mike brought 100 shares costing $53 each.
Total costs of shares= 100*53
=$5300
He got dividends of $1.45 per share. A dividend is money that is earnt back from a share.
Total dividend amount = 1.45*100
=$145
I'm assuming that Mike sold his shares at the end of the year. He sells for $60 each.
Total sales amount=60*100
=$6000
The rate of return in this instance can be defined as the amount of money made back from a share. 
Rate of return= total earnings/ costs
Total costs= $5300
Total earnings=$6145
6145/5300=1.1594
=15.9%
Hope this helps! :)
