Answer:
C. a) $348.75 b) $461.12
Step-by-step explanation:
Eli Katcher works 7¾ hours each day, Monday through Friday, then he works
[tex]7\dfrac{3}{4}\cdot 5=\dfrac{7\cdot 4+3}{4}\cdot 5=\dfrac{31}{4}\cdot 5=\dfrac{155}{4}[/tex]
hours per week.
The bottom pay is $9, then Eli can earn at least
[tex]\dfrac{155}{4}\cdot \$9=\$\dfrac{155\cdot 9}{4}=\$348.75[/tex]
The top pay is $11.90, tehn Eli can earn at most
[tex]\dfrac{155}{4}\cdot \$11.90=\$\dfrac{155\cdot 11.90}{4}=\$461.12[/tex]
