<em>Mr. avoid wants to build a doll house for his daughter that is proportional to their house you measure the living room of his house and it was 12’ x 16’ what will the dimensions of the doll house living room if every foot of the actual house equals 1/2 inch in the doll house </em>
My answer:
Given:
The living room of his house was 12’ x 16’ and this is the actual house
The dimensions of the doll house living room if every foot of the actual house equals 1/2 inch is:
<=> 1 foot = 1/2 inch
=> the dimensions of the doll house living room is:
12’ x 16’ = 6 inch * 8 inch

Step-by-step explanation:
30400=
30400=
\,\,22000e^{0.025t}
22000e
0.025t
Plug in
\frac{30400}{22000}=
22000
30400
=
\,\,\frac{22000e^{0.025t}}{22000}
22000
22000e
0.025t
Divide by 22000
1.3818182=
1.3818182=
\,\,e^{0.025t}
e
0.025t
\ln\left(1.3818182\right)=
ln(1.3818182)=
\,\,\ln\left(e^{0.025t}\right)
ln(e
0.025t
)
Take the natural log of both sides
\ln\left(1.3818182\right)=
ln(1.3818182)=
\,\,0.025t
0.025t
ln cancels the e
\frac{\ln\left(1.3818182\right)}{0.025}=
0.025
ln(1.3818182)
=
\,\,\frac{0.025t}{0.025}
0.025
0.025t
Divide by 0.025

Answer:
40 bats sold for $42
26 bats sold for $30
Step-by-step explanation:
x + y = 66
42x + 30y = 2460
solve first equation for y and plug in for y in second equation
42x + 30 (66 - x) = 2460
x = 40
y = 66- 40 = 26
