Step-by-step explanation: ...
Your answers will be A,B,D,
This is called diffusion.
14 will be your whole number and your fraction would be 63/100, so the entire thing as a mixed number is 14 63/100
Let u be the number of used cars and n the number of new cars, then u+n=17.
Sales values: 7000u+16000n=191000; so 7u+16n=191.
Since n=17-u, we can rewrite this: 7u+16(17-u)=191.
7u+272-16u=191, 9u=272-191=81 and u=9. So 9 used cars were sold (8 new).
