The fee Jack Duffy charges per mile is $0.278, making option B correct.

Detailed explanation:

Given:

Jack Duffy's travel distance = d = 12,568 miles

Fixed costs amount to = $1,485.00

Variable costs amount to = $2,015.75

Let the cost per mile charged by Jack Duffy be = $x

According to the provided information

Total cost = Fixed costs + Variable costs

Thus, Total cost = $1,485.00 + $2,015.75

This equates to Total cost = $3,500.75

Therefore,

The cost Jack Duffy charges per mile =

Hence, x = $0.278 per mile

This leads us to conclude that Jack Duffy’s charging rate is $0.278 per mile, confirming option B.

Answer: The hourly charge for the rototiller is $3.

Step-by-step explanation:

Let h denote the hourly rate for the rototiller rental.

The rental provider imposed a base fee of $43 in addition to a charge per hour. Assuming the rototiller was rented for x hours, the cost incurred would total

43 + hx.

If they paid $64 for 7 hours of rental, the equation representing this situation would be

43 + 7h = 64.

Resolving gives us 7h = 64 - 43 = 21.

Therefore, h = 21/7 = $3.

Answer:

1.4×10⁻⁵=0.000014

Step-by-step explanation:

Since the exponent of the 10 term is negative, shift the decimal point to the left by 5 positions;

1.4×10⁻⁵=0.000014

The total number of individuals surveyed is 280. From the survey results, 65% were satisfied with the park's condition. Given that this satisfied group represents 182 people, we can calculate the overall survey population using this information.
