Answer:
Step-by-step explanation:
From the question, since it will take 90 days that is 3 months for her hourly pay to increase to $8 per hour
we proceed to calculate her pay for the first 3 months
she works a total of 32 hours in a week
hence for three months, she would work 32*4*3= 384hours
therefore her pay for three months is= 7.5*384= $2880
Now the remaining one month her pay rate has been increased to $8 per hour
the number of hours in one month is 32*4= 128 hours
her pay would be 128*8= $1024
Her straight time pay for 4months is $2880+$1024 = $3904
