Answer:
Step-by-step explanation:
Let the amount creating equality = x
10% x + 625 = 20%x Convert The percentages to a decimal
10/100 x + 625 = 20/100 x Multiply both sides by 100
10x + 62500 = 20 x Subtract 10x from both sides
62500 = 20x - 10x Combine
62500 = 10x Divide by 10 on both sides
62500/10 =10 x/10
6250 = x
The equality is reached when 6250 sales is made.
<span>N = N0 e^(-kt)
for half life N/N0 = 1/2 and k = 0.1459
1/2 = e^(-0.1459t)
=> -0.1459 t = ln(0.5)
t = - ln(0.5) /0.1459
= 4.8 days </span>
