Answer: b
Step-by-step explanation:
The required scale model will be 1:6.24 10^9
<h3>Finding scale factors</h3>
A scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure.
Given the following parameters
Distance of sun to Jupiter = 7.8 * 10^8 km
If the distance of sun to Jupiter is 8m on his scale, hence the value of n is calculated as;
n = 8 * 7.8 *10^8
n = 62.4 * 1068
n = 6.24 10^9
Hence the required scale model will be 1:6.24 10^9

From the number 842 to 109 is a decrease of 733. so 109 minus 733 will result in a -624.
