Answer:
$42.07
Step-by-step explanation:
Let the price of the sweater =s
Let the price of the tie =t
The total cost of a sweater and a tie was $85.12.
s+t=85.12.
The price of the sweater was $0.98 less than the tie
t=s+0.98
Therefore:
s+s+0.98=85.12
2s=85.12-0.98
2s=84.14
s=$42.07
The price of a sweater is $42.07.
