Answer:
a). Money earned in a year=$17,727.60
He will have to work 150 hours or 3.75 weeks
Step-by-step explanation:
a). Money earned in a year
Assuming he works in a common year, where 1 year=365 days
1 week = 7 days
The number of weeks in a common year=365/7=52.14 weeks
Diez works 40 hrs a week
The number of hours he works in a year(52.14 weeks)= 52.14×40=2,085.6 hours
He is paid $8.50 per hour
The amount he earns in a year(2,085.6 hours)= 2085.6×8.5=17,727.60
b). How long he has to work to save $1275
Total earnings=Number of hours he works×Rate of earning per hour
where;
Total earnings=$1275
Number of hours he works=N
Rate of earning per hour=$8.50
1275=N×8.5
Solving for N
8.5N/8.5=1275/8.5
N=150 hours
1 week = 40 hrs
150/40=3.75 weeks
He will have to work 150 hours or 3.75 weeks
