the total cost of kurts required textbooks this quarter is $342.50. optional textbooks cost a total of $65.25. whicg inequality shows the total cost C that kurt could pay for his textbooks?

342.5 + 65.25 = C

407.75 = C

Step-by-step explanation:

Given that the total cost of Kurt's required textbooks this quarter is $ 342.50, while optional textbooks cost a total of $ 65.25, to determine which inequality shows the total cost C that Kurt could pay for his textbooks, the following mathematical reasoning must be performed:

Mandatory books + optional books = Cost

342.5 + 65.25 = C

407.75 = C

Thus, Kurt could pay a total cost of $ 407.75 for his textbooks this quarter.

area = 1385.44

circumference = 131.94

Step-by-step explanation:

area of circle is pi* (radius)^2

area= pi*21^2

area=3.14*441

area= 1385.44

Circumference of a circle is 2*pi*radius

C= 2*3.14*21=131.94
