Answer:
remainder = 122
Step-by-step explanation:
Using the remainder theorem to evaluate the remainder
Division by x - 3 , thus evaluate f(3) for remainder
f(3) = 3³ + 14(3)² - 7(3) - 10
= 27 + 126 - 21 - 10
= 122 ← remainder
1 3/4 hours of work equates to $18.375 so $18.38.
2 1/3 hours of work equates to $24.50.
1 5/12 hours of work equates to $14.875 so $14.88
Add all values $18.38+$24.50+$14.88 = $57.76
