Step-by-step explanation:

We have been given that Chole is buying 2/3 pound of ham and 3/5 as many pounds of cheese as ham.

First of all, we will find pounds of cheese bought by Chole by finding 3/5 of 2/3 as:

We are told that cheese cost $4.95 per pound. Let us find cost of 2/5 pounds of cheese by multiplying 2/5 by $4.95 as:

We are also told that ham cost 5/3 as much per pound as cheese. Let us find cost of per pound of ham by calculating 5/3 of $4.95 as:

Cost of 2/3 pound of ham would be $8.25 times 2/3 as:

Therefore, Chole will pay $7.48 for the cheese and ham.
