Answer: He is paid $90 last weekend.
Step-by-step explanation:
Since we have given that
Amount he earns per hour = $6
If he works on Saturday, he is paid time and a quarter .
Amount would be
[tex]6\times 1.25=\$7.5[/tex]
If he works on Sunday, he is paid time and a half.
Amount would be
[tex]6\times 1.5=\$9[/tex]
Number of hours he worked on Saturday = 6 hours
Number of hours he worked on Sunday = 5 hours
So, Total amount he is paid last weekend altogether is given by
[tex]6\times 7.5+5\times 9\\\\=\$90[/tex]
Hence, he is paid $90 last weekend.
