1. Just simply multiple the number of hours to the wage rate.

1st week: $9.4/h *(7 h + 1/4 h) = $68.15
2nd week: $9.4/h *(8 h + 3/4 h) = $82.25
3rd week: $9.4/h *(5 h + 1/2 h) = $51.7
4th week: $9.4/h *(6 h + 3/4 h) = $63.45

2. There are four week in the month. Since he puts half of his earning every week, we take into account the 2nd and 4th week earnings.

Money in the bank = $82.25/2 + $63.45/2 = $72.85

3. The rest of the money is assumed to be spent. Take the sum of all the earnings:

Total Earnings = 68.15+82.25+51.7+63.45 = $265.55
Thus, the earnings spent is
Earnings Spent = Total Earnings - Money in the bank
Earnings Spent = $265.55 - $72.85 = $192.7
