Answer:
$407.25
Step-by-step explanation:
We need to find her total salary for last week.
time-and-a-half means 1.5 * base wage
So, that would be 1.5 * 9 = 13.5 [this would be applied to hours over 40].
So, for 43.5 hours,
40 hours @ 9 per hour [40 * 9 = $360]
3.5 hours @ 13.5 per hour [3.5*13.5=$47.25]
Total Pay for last week = 360 + 47.25 = $407.25
