10p - 5c + 2p + 8c
= 10p + 2p - 5c + 8c
= (10+2)p + (-5+8)c
= 12p + (8-5)c
= 12p + 3c
Use proportionals to find y.

Step-by-step explanation:
Answer: The amount of carbon-14 remaining after 4 years is 99.95 grams.
Step-by-step explanation:
Hi, to answer this question we simply have to substitute t=4 in the equation given and solve for c.
c= 100 (0.99988)^t
c =100 (0.99988)^4
c = 100 x 0.999520086
c= 99.95200864 ≅99.95 grams (rounded)
The amount of carbon-14 remaining after 4 years is 99.95 grams.
