Please help me the picture is above I’ll mark you as the brainliest but please show the work. Thank you! :)

a) whatever is in the bracket you substitute into x.

c(100) = (1.25*100) + 2175

          = 125 + 2175

          = 2300

Another exmaple: if it says c(2 + x) then you substitute that into x

→ 1.25(2 + x) + 2175  (and then expand that)

b) A physical interpretation of this could be:

For every 1.25 w-widget that is produced, you would add $2175 for the other costs. (something like that)

$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

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
