At which site should Subway open the new restaurant? $(2$ marks$)$

Location A:

Space : $0\mathrm{.}30*60=18$

Costs : $0\mathrm{.}25*40=10$

Traffic Density : $0\mathrm{.}20*50=10$

Neighbourhood Income: $0\mathrm{.}15*50=7\mathrm{.}5$

Zoning Laws: $0\mathrm{.}10*80=8$

Location B:

Space : $0\mathrm{.}30*70=21$

Costs : $0\mathrm{.}25*80=20$

Traffic Density : $0\mathrm{.}20*80=16$

Neighbourhood Income: $0\mathrm{.}15*70=10\mathrm{.}5$

Zoning Laws: $0\mathrm{.}10*20=2$

Location C:

Space : $0\mathrm{.}30*80=24$

Costs : $0\mathrm{.}25*30=7\mathrm{.}5$

Traffic Density : $0\mathrm{.}20*60=12$

Neighbourhood Income: $0\mathrm{.}15*40=6$

Zoning Laws: $0\mathrm{.}10*90=9$

If the weights for Space and Traffic density are reversed, how would this affect the decision? $(2$ marks$)$
