This appears to be a composite function situation where you find the value of t(x) and sub that in for the x in c(x). If x = 4, then t(4) = 4(4) + 3 and t(4) = 19. Sub that 19 in for x in c(x) to get 2(19) + 5 which is 43. So 43
Answer:

Step-by-step explanation:
Let the percentage be x%,
then,
x% of 80 = 64
![\frac{x}{100} \times 80 = 64 \\ \frac{x}{10} \times 8 = 64 \\ \frac{x}{10} = \frac{64}{8} \\ x = 8 \times 10 = 80 \%](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B100%7D%20%20%5Ctimes%2080%20%3D%2064%20%5C%5C%20%20%5Cfrac%7Bx%7D%7B10%7D%20%20%5Ctimes%208%20%3D%2064%20%5C%5C%20%20%5Cfrac%7Bx%7D%7B10%7D%20%20%3D%20%20%5Cfrac%7B64%7D%7B8%7D%20%20%5C%5C%20x%20%3D%208%20%5Ctimes%2010%20%3D%2080%20%5C%25)
