2.7 mpg less than Evan's

Step-by-step explanation:

Riley gets 430.1 / 11 = 39.1 mpg

Evan gets 418 / 10 = 41.8 mpg

41.8 - 39.1 = 2.7

9514 1404 393

  2.7, less

Step-by-step explanation:

To find miles per gallon (MPG), divide miles by gallons.

  Riley's car:

     (430.1 mi)/(11 gal) = 39.1 mi/gal

  Evan's car:

     (418 mi)/(10 gal) = 41.8 mi/gal

__

Then the difference is ...

  41.8 -39.1 = 2.7 . . . miles per gallon

We note that Riley's MPG is less than Evan's, so we can write ...

  Riley's car gets 2.7 miles per gallon less than Evan's car.

correct answer:

b.(19,-2)

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
