patrica earn R45,50 per hour babysitting her friend helps her and patrica effers to pay her half her earnings.they babysit for 3 hours and 45 minutes
To calculate Patricia's earnings for the 3 hours and 45 minutes of babysitting, first convert the 45 minutes to hours. Since there are 60 minutes in an hour, 45 minutes is equal to 45/60 = 0.75 hours.
Now add the 3 hours and 0.75 hours together:
3 hours + 0.75 hours = 3.75 hours
Next, calculate Patricia's total earnings by multiplying her hourly rate of R45.50 by the total number of hours worked:
Total earnings = Hourly rate x Total hours
Total earnings = R45.50 x 3.75
Total earnings = R170.63
Lastly, since Patricia offered to pay her friend half of her earnings, calculate half of R170.63:
Half of earnings = Total earnings / 2
Half of earnings = R170.63 / 2
Half of earnings = R85.31
Therefore, Patricia's friend will receive R85.31 for helping her babysit for 3 hours and 45 minutes.
