Answer:
C. 1/5
Step-by-step explanation:
Original * scale factor = Scaled
25 * SF = 5
Divide each side by 25
25/25 * SF = 5/25
SF = 1/5
100-0.0124=99.9876
10%=1/10
1/10P=P(0.999876)^t
divide both sides by P
1/10=0.999876^t
take ln of both sides
ln(1/10)=t (ln(0.999876))
divide both sides by (ln(0.999876))
ln(1/10)/(ln(0.999876))=t
use calculator
18568.08=t

<u>85 + c/4 = 99</u>
Subtract 85 from each side: c/4 = 14
Multiply each side by 4 : <em> c = 56
</em>
12(0.57)= 6.84
10-6.84= 3.16
Mr. Turner’s change is $3.16.
Hope this helps!
