You pay $300 for an antique lamp. The lamp is expected to appreciate every of about 8% annually At this rate, how long will it take for the value of the lamb to double

it will take 9 years for the value of the lamb to double.

Step-by-step explanation:

The growth rate is exponential. We would apply the formula for exponential growth which is expressed as

y = b(1 + r)^ t

Where

y represents the value of the lamb after t years.

t represents the number of years.

b represents the initial value of the lamb.

r represents rate of growth.

From the information given,

b = $300

y = 2 × 300 = $600

r = 8% = 8/100 = 0.08

Therefore

600 = 300(1 + 0.08)^t

600/300 = (1.08)^t

2 = (1.08)^t

Taking log of both sides to base 10

Log 2 = log1.08^t = tlog1.08

0.3010 = t × 0.0334

t = 0.3010/0.0334

t = 9 years

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

step-by-step explanation:

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
