Answer 1

Answer: $174.09

Step-by-step explanation:

$16.80 times 8.5 hours equals 142.8 plus $31.29 equals $174.09

Answer 2

• Flat fee=$31.29
• Per hour fee=$16.80

Function is

$\\ \sf\longmapsto C=31.29+16.8h$

• h=8.5

$\\ \sf\longmapsto C=31.29+16.8(8.5)$

$\\ \sf\longmapsto C=31.29+142.8$

$\\ \sf\longmapsto C=\ 174.1$
