The school council sold small and large sandwiches for a fun

The school council sold small and large sandwiches for a fundraiser. In the first hour, they raised $48 by selling eight small sandwiches and $32 by selling four large sandwiches. If the amount charged for each size of sandwich remains constant, how much additional money would the school council raise by selling another 14 large sandwiches? A $144 B $112 C $84 D $80

Solution

cost of eight small sandwiches= 48 dollars

cost of four large sandwiches= 32 dollars

cost of 1 large sandwich=32/4=8 dollars

cost of additional 14 large sandwiches=14 x 8 = 112 dollars

hence the correct option is ans (B)
