b) 55 people said their favorite vehicle color was either black or silver
Step-by-step explanation:
(a). How many more people said their favorite vehicle color was blue compared to those who said white explain?
250 people
32% said blue. 32% of 250 is 0.32*250 = 80
24% said white. 24% of 250 is 0.24*250 = 60
80 - 60 = 20
20 more people said their favorite vehicle color was blue compared to those who said white.
(B) how many people said their favorite vehicle color was either black or silver ?
18% said black, 4% said silver.
18 + 4 = 22% of 250 = 0.22*250 = 55
55 people said their favorite vehicle color was either black or silver

Answer:
a) T= 0.25 C+37
b) T= 62°F
Step-by-step explanation:
Here T is a linear function of C
T= mC+b
For each additional chirp C corresponding to an increase in T of 0.25
therefore, m= 0.25
T= 42° F C=20 ( given)
therefore,
a) 42= 0.25×20+b
b= 37
therefore T= 0.25 C+37
b) now C= 100
therefore, T= 0.25×100+37 = 62°F
