At an ice cream store, a family ordered 6 banana splits and 3 hot fudge sundaes, paying a total of $45 for their order. The next customer ordered 1 banana split

Question

I need help with this problem it is confusing and I do not understand

 

Answer 1

you need to find the cost the next cusomer paid for the banana split.....   Then mulitiply that by 6 and subtract it from the $45 the first customer paid.  That leaves you with what the first customer paid for 3 hot fudge sundaes.  Divide that result by 3, and you'll have the cost of a HF Sundae.
