Answer:
D
Cost of one scarf= $7
Cost of one hat= $4
Explanation:
Let s represents the cost of scarfs
and h represents the cost of hats.
Cost of four scarfs and six hats is $52.00
i.e. 4s+6h=52
Cost of two hats is $1.00 more than the cost of one scarf.
i.e. 2h=s+1
s=2h-1
substituting s in 4s+6h=52
4(2h-1)+6h=52
8h-4+6h=52
14h=56
h=4
s=2h-1
s=8-1
s=7
Hence,
Cost of one scarf= $7
and Cost of one hat= $4
