A group of students purchase ice cream cones and ice cream sundaes. The cones cost $1.40 each, and the cost for $19$ sundaes is $64.60. The total cost for the cones and sundaes is $85.60. Which equation represents this situation, where $x$ is the number of cones purchased and $y$ is the number of sundaes purchased?

A

$1.40x+64.60y=85.60$

B

$64.60x+1.40y=85.60$

C

$3.40x+1.40y=85.60$

D

$1.40x+3.40y=85.60$
